Wikipedia Describes the Packet Radio Van: Disagreements | Network, Not Protocol

On November 12, 2026, Mark Nichols set the Wikipedia article Packet Radio Van, as revised on November 3, 2026, against dated documents and found six of its statements false as written, among them its claim that the van's demonstration of November 22, 1977 was "The first true Internet transmission," because the article's own principal source, Don Nielson of SRI International, wrote that the event "has come to be more generally regarded as the first internet transmission" and dated the first transmission across two networks to August 27, 1976.

Preamble: I created this page to examine how the Wikipedia article Packet Radio Van, in its revision of November 3, 2026, describes the van of SRI International and the transmissions of August 27, 1976 and November 22, 1977. The page tests the article's claim that the transmission of November 22, 1977 "is considered the start of the Internet," its description of internetworking as "connecting different communications protocols via the Internet protocol suite," its claims that the van took part in "the very first demonstration of the Internet" and in "The first true Internet transmission," its description of the van as "an ARPANET node via packet radio," its naming of the transmission of 1976 as "TCP/IP," its account of the route of November 22, 1977, its credit to the van for "the first experiments" with "Voice over IP," and its account of the van's return in 1997 and of the celebration of 2007. The page also records the statements of the article that the documents support. Each disagreement on this page cites the article's line by its number in Exhibit A in section 12.0 and names the dated document that decides it. Wikipedia, Packet Radio Van, revision 1383611727 · The Governing Definitions and Controlling Facts of Telecommunications Internetworking. This page is Disagreement 65 in the standing index of the series, Disagreements of Published Claims | Network, Not Protocol, and a finding on this page is cited by that number followed by the finding's locus, as Disagreement 65, 1.1.

0.0 This section records the revision of the Wikipedia article this page examines, the sources this page read, the way the line numbers on this page are read, the definitions and rules the findings apply, the audit of the article as an authority, and the order of the sections that follow.

0.1 This page examines the Wikipedia article Packet Radio Van on en.wikipedia.org in revision 1383611727. Wikipedia's revision history records that revision 1383611727 was saved on November 3, 2026 at 18:02 (UTC), which is November 3, 2026 in Pacific time, by the account "GreenC bot," with the edit summary "Move 1 url. [[User:GreenC/WaybackMedic_2.5|Wayback Medic 2.5]] per [[WP:URLREQ#news.cnet.com]] PassA." Wikipedia's page information for the article, read on November 12, 2026, recorded revision 1383611727 as the latest revision of the article and recorded no protection on it. The revision of November 3, 2026 moved one link, and the accounts that wrote the sentences this page answers are not recorded in the revision this page reproduces, so they are stated on this page as unknown. The text of the article is attributed to Wikipedia contributors under CC BY-SA 4.0.

0.2 This page read the following sources in full on November 12, 2026, and it states for each source that it did not read that the source was not read.

The article's reference at line 25, Don Nielson's "The SRI Van and Computer Internetworking," published in CORE, Vol. 3, No. 1, by the Computer History Museum in February 2002, was read in the transcription at ed-thelen.org, which describes itself as "most of an article about the role of an SRI van in the development of internetworking." The archived PDF of CORE that the article links was not read, and every quotation of Don Nielson on this page is quoted from the transcription, with its misprints as printed.
The article's reference at line 30, Erica Ogg's "‘Internet van’ helped drive evolution of the Web," published by CNET on November 8, 2007, was read in full at cnet.com.
The address that the article gives for its reference at line 31, SRI International's "Timeline of innovations: Internetworking: The First Three-Network Transmission," redirected on November 12, 2026 to SRI International's page "Internetworking," which was read in full.
The Computer History Museum's press release of November 1, 2007, "Computer History Museum and Web History Center Celebrate 30th Anniversary of Internet Milestone," which the article does not cite, was read in full at computerhistory.org.
The article's references at lines 24, 26, 27, 28 and 29 were not read: Andreu Veà Baró's book Como hicimos Internet of 2013, the SRI Alumni Association Newsletter of December 2010, the SRI Alumni Association Newsletter of August 2011, David Laws's "Alpine Inn & Beer Garden," and Linda Hubbard Gulker's article of December 30, 2019. This page makes no finding on what those sources say.

0.3 Each line number on this page refers to Exhibit A in section 12.0. Exhibit A lists the text of revision 1383611727 line by line, in the order the article prints it, under the names of the article's own sections. Each disagreement also quotes the line it answers.

0.4 The capital-I Internet (D1) is the publicly joinable network of networks of the registry lineage, whose addresses and autonomous system numbers were issued by the InterNIC and are maintained today by ARIN. On that network, a person can buy access from competing providers for lawful purposes, and an independent network can obtain addresses and an autonomous system number and interconnect by agreement with a willing network, without the permission of a central owner or the sponsorship of a government. An intranet (D2) is a network, at any scale and under any protocol, whose members join by an owner's permission. Internetworking (D3) is the technique of interconnecting distinct networks through gateways so that traffic originating on one network can reach hosts on another. A lowercase internet (D11) is any interconnection of networks, including gated ones, and the capital I in this site's own prose means the publicly joinable network of the registry lineage born in 1991 and nothing else. Governing Definitions, D1, D2, D3, and D11.

0.5 This page answers three kinds of disagreement, and each disagreement on this page names the kind that applies.

A documentary contradiction occurs when a dated record conflicts with a line as written. This page answers it with the dated record and a dated correction.
A scope overstatement occurs when the evidence establishes a narrower event, network, date or function than the line claims. This page answers it with the scope the evidence establishes.
A definitional disagreement occurs when the article and this site apply different criteria to the same term. This page answers it by attributing each usage to its source.

Under D6, the Internet protocols are the optional protocols TCP and IP, utilities whose messages the networks carry, and the optional protocols TCP and IP are not the networks and are not the Internet. The van of SRI International was a mobile node of a radio network, and the transmissions it originated were carried by the packet radio network, the gateways and the networks beyond them, so this page names each transmission by the networks that carried it. Governing Definitions, D6.

0.6 The article has no author of record. This page applies to it the five checks that Mark Nichols ruled on October 2, 2026, and extended on October 23, 2026, for every authority a page cites or disputes, and the five checks return the following results.

The issuing body's membership rule is Wikipedia's editing rule, and Wikipedia's page information of November 12, 2026 recorded no protection on the article, so any account that Wikipedia admits may edit it.
The roster on the date of the act is the account that saved revision 1383611727, the account "GreenC bot," whose edit moved one link, and the accounts that wrote the sentences this page answers are not recorded in that revision, so this record states them as unknown.
The instrument carries no named author and no vote, because a Wikipedia revision is saved by one account and adopted by no body.
The custodian is the Wikimedia Foundation, which serves the article at en.wikipedia.org as a text that changes with every saved revision, so the article is a living text and not a dated instrument, which is why 0.1 fixes the revision by its number and its date.
The overlap between the article's authors and the author of this page cannot be computed, because this page names its author, Mark Nichols, and the article names no author. The overlap between the sources the article relies on and the event they describe is recorded here as a finding. Don Nielson, whose article the article cites six times, was the principal investigator of SRI International for ARPA in the early stages of the packet radio program, as his own article states. SRI International, whose page calls the connection of 1977 "the first true Internet connection," built the van, and the Computer History Museum, whose press release of November 1, 2007 calls the connection "widely regarded as the first true Internet connection," holds the van, which SRI International gave it. That press release lists Vinton Cerf and Robert Kahn of DARPA among the seven participants on its panel, and it names Cisco Systems, SRI International and Rockwell Collins as the co-sponsors of the celebration of November 7, 2007. CNET's article of November 8, 2007 quotes Vinton Cerf and describes him as working "as the chief Internet evangelist for Google." This page makes no finding on why any of these overlaps exists.

Under D12, contemporaneous primary documents control over retrospective accounts. The article is a retrospective account with no author of record, so no line of the article is carried on this page as controlling. Every disagreement below is decided by the dated document that the disagreement names, and not by the standing of the article. Governing Definitions, D12.

0.7 Under F56, Mark Nichols ruled on October 23, 2026 that a sentence of history or of definition is true or false as written. This page reads every line of the article as written. The meaning an author may have intended but did not write is not in the record, and a line whose predicate is false as written is false, whether the falsity arose from compression, from shorthand or from intent. Each corrected statement on this page supplies the network, the document, the date or the event that the line left out. Governing Definitions, F56.

0.8 Sections 1.0 through 9.0 each state one disagreement, in the order of the article's own lines.

Section 1.0 answers the claim at line 3 that the transmission of November 22, 1977 "is considered the start of the Internet."
Section 2.0 answers internetworking described at line 6 as "connecting different communications protocols via the Internet protocol suite."
Section 3.0 answers the claims at line 7 and line 13 that the van took part in "the very first demonstration of the Internet" and in "The first true Internet transmission."
Section 4.0 answers the van described at line 8 as carrying "all of the equipment needed to be an ARPANET node via packet radio."
Section 5.0 answers the transmission of August 27, 1976 named at line 11 as "The first two-network TCP/IP transmission."
Section 6.0 answers the route of November 22, 1977 described at line 14.
Section 7.0 answers the credit at line 15 to the van as "the site of the first experiments" with "Voice over IP."
Section 8.0 answers the account at lines 18 and 19 of the van's return in 1997.
Section 9.0 answers the citation that line 22 gives for the celebration of 2007.

Section 10.0 records the statements of the article that the documents support. Section 11.0 states the findings of this page and their consequences for the article as an authority. Section 12.0 holds Exhibit A, the numbered text of revision 1383611727.

1.0 Line 3 says that the transmission of November 22, 1977 "is considered the start of the Internet," which is a definitional disagreement, because the article names no one who considers it so, and the article's own principal source records that the designation began in 1996 and calls the first transmission of all a matter that is "somewhat arbitrary."

1.1 Line 3 of the article says: "The Packet Radio Van was a GMC Value-Van refitted by Don Cone at SRI International, and equipped with technology that was used in the first two-way internetworked transmission on August 27, 1976, and the first three-way internetworked transmission on November 22, 1977, the latter of which is considered the start of the Internet." The line cites one source, Andreu Veà Baró's Como hicimos Internet of 2013, at page 172, which this page did not read.

1.2 Mark Nichols disputes the words "is considered the start of the Internet." The line reports a view and does not name who holds it, and the dated record shows when and by whom the view was formed. This is a definitional disagreement under D1.

1.3 Don Nielson writes, in the afterword of "The SRI Van and Computer Internetworking" of February 2002: "The possible importance of "the van" began to surface sometime in 1996 when an IEEE Spectrum editor called and mentioned that Vint Cart had said in an interview that "SRI was the site of the first internet transmission."" The name "Cart" is printed so in the transcription, and the interview is not otherwise identified there. Don Nielson continues that after "the November 1977 date was confirmed and defined accurately and had been promulgated a bit," the next call came from The Computer Museum History Center "about celebrating the 20th anniversary of the Internet at the Supercomputer Conference in San Jose in 1997." CNET's article of November 8, 2007 records the same order of events: "It wasn’t until 1996, when an editor with the Institute of Electrical and Electronics Engineers called to ask about the first transmission on that November day in 1977, that Nielson realized that driving the beat-up van around the Bayshore Freeway was a seminal event in the advancement of the Internet." Don Nielson, "The SRI Van and Computer Internetworking" · CNET, November 8, 2007.

1.4 Don Nielson writes in the same afterword: "Identifying the first of anything that is created in collaborative way is somewhat arbitrary." He continues: "Then there is the question of how many networks it takes to qualify as "internet." In this we have chosen first the minimum number-two-and then about a year later-three." His article calls the event of August 27, 1976 "the first internet transmission," and it calls the event of November 22, 1977 "what has come to be more generally regarded as the first internet transmission." The words "come to be more generally regarded" record a convention that formed after the event.

1.5 The bodies that hold the view are named in their own documents. SRI International's page "Internetworking" says of the connection of 1977: "This connection is considered to be the first true Internet connection." The Computer History Museum's press release of November 1, 2007 calls it "widely regarded as the first true Internet connection." The same two bodies date the debut of internetworking differently. SRI International says: "Internetworking made its formal debut in 1976, when SRI established the first connection between two dissimilar networks." The Computer History Museum says: "This kind of internetworking made its formal debut with the three-network transmission that occurred on November 22, 1977." SRI International, "Internetworking" · Computer History Museum, November 1, 2007.

1.6 Under D1, the Internet, with a capital I, is the publicly joinable network of networks of the registry lineage born in 1991, and a view formed in 1996 and 1997 by the builder and the later holder of the van does not change the date of the network's birth. Governing Definitions, D1.

1.7 This section records a definitional disagreement under D1 and does not count line 3 among the false-as-written verdicts. SRI International and the Computer History Museum do consider the connection of 1977 the first true Internet connection, so the words "is considered" report a view that two named bodies hold, and the disagreement lies in the view and in the line's silence on who holds it.

1.8 Corrected statement: On November 22, 1977, the packet radio van of SRI International originated the first transmission across three dissimilar networks, the packet radio network, the ARPANET and the Atlantic satellite network, which SRI International and the Computer History Museum call the first true Internet connection. The designation of the event as the first Internet transmission surfaced in 1996, by the account of Don Nielson of SRI International, and the Internet, with a capital I, the publicly joinable network of networks of the registry lineage, was born in 1991.

2.0 Line 6 says that internetworking meant "connecting different communications protocols via the Internet protocol suite," which is false as written, because the article's own principal source says that the protocol "was designed to carry information over dissimilar networks," and records that the Internet Protocol had not yet been separated from it.

2.1 Line 6 of the article says: "As DARPA further wished to connect the disparate computers at its various contractors, and indeed globally, there was a push to test internetworking - connecting different communications protocols via the Internet protocol suite." The line carries no citation of its own.

2.2 Mark Nichols disputes the definition. Internetworking connected networks, not protocols, and the protocol of 1976 and 1977 was one program, not a suite. This is a documentary contradiction, decided by the article's own principal source.

2.3 Don Nielson writes: "TCP was designed to carry information over dissimilar networks, in this case the PRNET, through a gateway at SRI, then across the ARPANET to a set of hosts distributed around the United States." SRI International's page "Internetworking" says that SRI "established the first connection between two dissimilar networks" and that "SRI connected the wired ARPANET with SRI’s wireless packet radio network." Under D3, internetworking is the technique of interconnecting distinct networks through gateways, and the things connected in 1976 and 1977 were networks. Governing Definitions, D3.

2.4 Don Nielson writes that the overhead of TCP "was deemed excessive for some types of traffic," and that "This soon led to a companion transaction protocol called the Internet Protocol (IP)." He writes of the speech experiments of SRI International that "these requirements for packet speech influenced the decomposition of the protocol into reliable or guaranteed (TCP) and non- guaranteed (IP) services," with the space after "non-" printed so in the transcription. Jon Postel's IEN 2, which first proposed "a new distinct internetwork protocol," is dated August 15, 1977, and section 4.0 of Wikipedia Defines the Internet Protocol Suite: Disagreements | Network, Not Protocol records that Wikipedia's own article Internet protocol suite dates the split of the Transmission Control Program into IP and TCP to version 4 of 1978. IEN 2, August 15, 1977.

2.5 Line 6 of the Wikipedia article Packet Radio Van, revision 1383611727 of November 3, 2026, is false as written under F56, because the internetworking that the van tested connected dissimilar networks through gateways, as Don Nielson and SRI International record, and because the Internet Protocol of the suite that line 6 names was first proposed as a separate protocol on August 15, 1977 and split from the Transmission Control Program in 1978. Governing Definitions, F56.

2.6 Corrected statement: DARPA's push to test internetworking was a push to connect dissimilar networks, the packet radio network and the ARPANET in 1976 and the packet radio network, the ARPANET and the Atlantic satellite network in 1977, through gateways built by Bolt Beranek and Newman, with the Transmission Control Program running in the hosts at the ends. The Internet Protocol was first proposed as a separate protocol in IEN 2 of August 15, 1977 and was split from the Transmission Control Program in 1978.

3.0 Line 7 says that the van "played a unique role in the very first demonstration of the Internet," and line 13 says that "The first true Internet transmission occurred on November 22, 1977," which are false as written, because the article's own principal source calls the transmission of August 27, 1976 "the first internet transmission," and the three networks of November 22, 1977 each admitted their members by the permission of a government sponsor.

3.1 Line 7 of the article says: "The van played a unique role in the very first demonstration of the Internet." Line 13 says: "The first true Internet transmission occurred on November 22, 1977, when SRI originated the first connection between three disparate networks." Line 7 cites Don Nielson's article of February 2002, and line 13 sits in a paragraph that cites CNET's article of November 8, 2007.

3.2 Mark Nichols disputes both lines. Line 7 names a demonstration of the Internet, and line 13 names a transmission of the Internet, and neither event was an event of the Internet. This is a documentary contradiction with the article's own sources and a definitional disagreement under D1, D2 and D11.

3.3 The article's own line 3 calls the event of August 27, 1976 "the first two-way internetworked transmission" and the event of November 22, 1977 "the first three-way internetworked transmission." Don Nielson, the source that line 7 cites, writes that the event of August 27, 1976 marked "the occasion of the first internet transmission," and that "dissimilar networks were bridged by TCP, thus clearly creating a two-network internet connection." His word is the lowercase internet, which under D11 is any interconnection of networks, including gated ones. CNET, the source of line 13's paragraph, writes of the celebration of 2007 that it was "marking the very first true Internet connection," and CNET names no document for the words.

3.4 SRI International's page "Internetworking" says of the ARPANET: "While the Internet’s origins can be traced to the ARPANET of the late 1960s, that was a single, closed network." Don Nielson writes that "PRNET was sponsored at SRI by ARPA (Advanced Research Projects Agency)," and the Computer History Museum's press release of November 1, 2007 records that the packet satellite network was "Implemented by Linkabit Corporation, BBN, and others between England, Sweden, and the United States." Section 4.0 of Wikipedia Defines the Internet Protocol: Disagreements | Network, Not Protocol records that the packet radio network, the ARPANET and the Atlantic satellite network of November 1977 each admitted its members by the permission of a government sponsor. Under D2, a network whose members join by an owner's permission is an intranet, and the connection of three research intranets on November 22, 1977 was an internet in lowercase under D11. Governing Definitions, D2 and D11.

3.5 Line 7 of the Wikipedia article Packet Radio Van, revision 1383611727 of November 3, 2026, is false as written under F56, because the demonstration that line 7 names was a demonstration of internetworking between research intranets, which the source that line 7 cites calls an "internet connection" in lowercase, and not a demonstration of the Internet. Line 13 of the same revision is false as written under F56, because the transmission of November 22, 1977 crossed three government-sponsored research intranets, and because the article's own line 3 and its own principal source place the first internetworked transmission on August 27, 1976. Governing Definitions, F56.

3.6 Corrected statement: The van of SRI International originated the first transmission between two dissimilar networks, the packet radio network and the ARPANET, on August 27, 1976, and the first transmission across three dissimilar networks, the packet radio network, the ARPANET and the Atlantic satellite network, on November 22, 1977. Both transmissions joined research intranets sponsored by ARPA and are events of internetworking, an internet in lowercase under D11, and the Internet, with a capital I, the publicly joinable network of networks of the registry lineage, was born in 1991.

4.0 Line 8 says that the van contained "all of the equipment needed to be an ARPANET node via packet radio," which is false as written, because the article's own principal source says that the van carried "the equipment needed to make it a portable node on the emerging Packet Radio Network (PRNET)," and that it reached the ARPANET through a gateway.

4.1 Line 8 of the article says: "The GMC van, designed by Don Cone, resembled a bread van and contained all of the equipment needed to be an ARPANET node via packet radio, including a Digital Equipment Corporation DEC LSI-11 16-bit minicomputer." The line cites Don Nielson's article of February 2002.

4.2 Mark Nichols disputes the words "an ARPANET node via packet radio." The van was a node of the packet radio network, and its traffic entered the ARPANET at a gateway. This is a documentary contradiction with the source that line 8 cites and with the article's own line 5.

4.3 Don Nielson writes: "The van was an SRI outfitted mobile radio lab that contained the equipment needed to make it a portable node on the emerging Packet Radio Network (PRNET)." He writes that the transmission of 1976 went "through a gateway at SRI, then across the ARPANET," and that "the bidirectional ARPANET gateway software, built by Ginny Strazisar at BBN," was located at the Packet Radio station. The article's own line 5 says that the van "housed one of the PRNET radio nodes." The ARPANET's own nodes were its Interface Message Processors, which Don Nielson calls "the massive, seemingly nuclear-hardened early IMPS," and the van carried no IMP.

4.4 Line 8 of the Wikipedia article Packet Radio Van, revision 1383611727 of November 3, 2026, is false as written under F56, because the source that line 8 cites says that the van's equipment made it "a portable node on the emerging Packet Radio Network (PRNET)," and because the van's traffic reached the ARPANET through a gateway at SRI International and not as a node of the ARPANET. Governing Definitions, F56.

4.5 Corrected statement: The van of SRI International contained the equipment needed to make it a mobile node of the packet radio network of the San Francisco Bay Area, including a Digital Equipment Corporation LSI-11 computer that ran the Transmission Control Program, and its traffic reached the ARPANET through a gateway, whose software Ginny Strazisar of Bolt Beranek and Newman built.

5.0 Line 11 calls the transmission of August 27, 1976 "The first two-network TCP/IP transmission," which is false as written, because the article's own principal source records the event as "the first formal use of the internet protocol known as "TCP,"" and the Internet Protocol was not separated from the Transmission Control Program until 1978.

5.1 Line 11 of the article says: "The first two-network TCP/IP transmission was between the van and ARPANET on August 27, 1976; the van was parked next to Rossotti's (since 1956, officially the "Alpine Inn"), a well-known Portola Valley, California biker bar, and wires were run to one of the picnic tables." The line cites David Laws's "Alpine Inn & Beer Garden" and Linda Hubbard Gulker's article of December 30, 2019, which this page did not read.

5.2 Mark Nichols disputes the name "TCP/IP." The protocol of August 27, 1976 was one program, and the name of the pair did not yet describe anything that existed. This is a documentary contradiction.

5.3 Don Nielson writes that the long e-mail report of August 27, 1976 was, "in a ceremonial sense, the first internet transmission; that is, the first formal use of the internet protocol known as "TCP."" He writes that the transmission went from "the PRNET, through a gateway at SRI, then across the ARPANET to a set of hosts distributed around the United States." He writes that the overhead of TCP, which "was deemed excessive for some types of traffic," led to "a companion transaction protocol called the Internet Protocol (IP)." As 2.4 records, IP was first proposed as a separate protocol in IEN 2 of August 15, 1977, and Wikipedia's own article Internet protocol suite dates the split to version 4 of 1978. The event of August 27, 1976 also ran between the packet radio network and the ARPANET, and not between the van and the ARPANET, because the van was a node of the packet radio network, as section 4.0 records.

5.4 Line 11 of the Wikipedia article Packet Radio Van, revision 1383611727 of November 3, 2026, is false as written under F56, because the transmission of August 27, 1976 used the Transmission Control Program, which Don Nielson calls "the internet protocol known as "TCP,"" and the Internet Protocol was first proposed as a separate protocol a year later and split from the Transmission Control Program in 1978. Governing Definitions, F56.

5.5 Corrected statement: On August 27, 1976, SRI International sent the weekly report of ARPA's Packet Radio Program from a terminal on a courtyard table beside the van, through the packet radio network, a gateway at SRI and the ARPANET, by the Transmission Control Program, which was the first transmission between two dissimilar networks. The Internet Protocol was first proposed as a separate protocol on August 15, 1977 and split from the Transmission Control Program in 1978.

6.0 Line 14 says that data "flowed seamlessly through the mobile van at SRI in Menlo Park," which is a documentary finding, because the Computer History Museum's sentence that line 14 follows has the data flow "from the van to a gateway at SRI," and the source that line 14's paragraph cites places the van on a freeway and not at SRI.

6.1 Line 14 of the article says: "Data flowed seamlessly through the mobile van at SRI in Menlo Park, California and the University of Southern California in Los Angeles via London, England, across three types of networks: packet radio, satellite, and the ARPANET." The line's paragraph cites CNET's article of November 8, 2007.

6.2 Mark Nichols records the route as a finding. The words "the mobile van at SRI in Menlo Park" can be read as the van of SRI or as a van located at SRI, and the route they describe leaves out the gateway and the host. This is a documentary finding on the route.

6.3 The Computer History Museum's press release of November 1, 2007 says: "The key event occurred on November 22, when data flowed seamlessly from the van to a gateway at SRI in Menlo Park, Calif. and eventually to a host at the University of Southern California in Los Angeles via London, England, across three types of networks: packet radio, satellite, and the ARPANET." Line 14 carries the same words with "from the van to a gateway at SRI" replaced by "through the mobile van at SRI" and with "eventually to a host at" removed. CNET's article of November 8, 2007 says that the van "would drive up and down Interstate 280 in the San Francisco Bay Area," and that the data traveled "from the van near San Francisco to the University of Southern California’s Information Sciences Institute in Los Angeles." SRI International's page "Internetworking" says: "On November 22, 1977, the antenna of an SRI van cruising the streets of the San Francisco Bay Area transmitted data between SRI in Menlo Park and the University of Southern California in Los Angeles via London, England, across three types of networks: packet radio, satellite, and the ARPANET."

6.4 Section 5.0 of Vint Cerf's "Internet ca 1977", an Incorrect Title on an Illogical Network Diagram: Disagreements | Network, Not Protocol traces the route from the operating figure of SRI International's "Progress Report on Packet Radio Experimental Network" of February 1978: from the van through the packet radio network, across a gateway into the ARPANET, through the Atlantic satellite network by way of London, and back onto the ARPANET to the host at the Information Sciences Institute of the University of Southern California.

6.5 This section records a documentary finding and does not count line 14 among the false-as-written verdicts. On the reading that places the van at SRI, line 14 is contradicted by CNET and by SRI International, which place the van on the roads of the San Francisco Bay Area, and on either reading line 14 leaves out the gateways and the host through which the data passed.

6.6 Corrected statement: On November 22, 1977, data flowed from the van of SRI International, moving on the roads of the San Francisco Bay Area, through the packet radio network to a gateway, into the ARPANET, through the Atlantic satellite network by way of London, and back onto the ARPANET to a host at the Information Sciences Institute of the University of Southern California in Los Angeles.

7.0 Line 15 says that the van was "the site of the first experiments" with "Voice over IP" around 1977 to 1978, which is false as written, because the article's own principal source records that packet speech was first tried over the ARPANET after 1974, that the van became "the first mobile node for packet speech experiments," and that the speech experiments helped bring the separate Internet Protocol into being.

7.1 Line 15 of the article says: "The van was also the site of the first experiments (primarily by Earl Craighill and Tom Magill) with Voice over IP through ARPA's Network Speech Compression Program around 1977 to 1978." The line's paragraph cites Don Nielson's article of February 2002.

7.2 Mark Nichols disputes the words "the first experiments" and "Voice over IP." The first packet speech experiments were not in the van, and the experiments in the van came before the protocol whose name line 15 gives them. This is a documentary contradiction with the source that the paragraph cites.

7.3 Don Nielson writes: "In 1974, Kahn Initiated the Network Speech Compression Program because of the narrow bandwidth of the initial circuits comprising the net. This program resulted in the choice of some compression algorithms and these were first tried over the ARPANET." He writes: "In 1976, SRI's Earl Craighill and Tom Magill, both of whom had been working on the speech program, convinced ARPA to let them try speech on the Bay Area PRNET." He writes that the van "became the first mobile node for packet speech experiments." He writes that "these requirements for packet speech influenced the decomposition of the protocol into reliable or guaranteed (TCP) and non- guaranteed (IP) services," and that "internet speech connections were being conducted as early as 1977-1978." By his account, the first packet speech experiments ran over the ARPANET, the van was the first mobile node, and the speech work helped cause the separation of IP, so the speech of 1977 and 1978 was not carried over IP as a separate protocol.

7.4 Line 15 of the Wikipedia article Packet Radio Van, revision 1383611727 of November 3, 2026, is false as written under F56, because the source that its paragraph cites records that packet speech was first tried over the ARPANET under the Network Speech Compression Program of 1974, that the van was the first mobile node for packet speech experiments, and that the requirements of packet speech influenced the separation of IP from TCP, so the experiments in the van were neither the first experiments nor experiments with Voice over IP. Governing Definitions, F56.

7.5 Line 17 says: "The phone in the van was a Mickey Mouse phone." Don Nielson's caption says that "The Mickey Mouse phone was deliberately used to illustrate that the speech equipment hardware and software was designed to accommodate standard, off-the-shelf telephone," and the caption does not say where the phone was. This page makes no finding on line 17.

7.6 Corrected statement: Packet speech was first tried over the ARPANET under the Network Speech Compression Program that Robert Kahn of ARPA started in 1974. In 1976, Earl Craighill and Tom Magill of SRI International persuaded ARPA to let them try speech on the packet radio network of the San Francisco Bay Area, the van became the first mobile node for packet speech experiments, and the requirements of packet speech influenced the separation of IP from TCP.

8.0 Lines 18 and 19 say that the van was restored for "a celebration of the 20th anniversary of the Internet in 1997 at the Internet Supercomputer Conference" and that its "radio and Internet equipment" was replenished, which records a definitional disagreement and two documentary findings, because the article's own principal source names the conference "the Supercomputer Conference" and says that its restorers were "trying to replenish" the equipment.

8.1 Line 18 of the article says: "The van was parked unused for a decade in a back lot of the SRI campus until the planning of a celebration of the 20th anniversary of the Internet in 1997 at the Internet Supercomputer Conference in San Jose, California." Line 19 says: "SRI employees Don Alves and Don Nielson cleaned, licensed, and replenished the van's radio and Internet equipment." The paragraph cites Don Nielson's article of February 2002.

8.2 Mark Nichols disputes the words "the 20th anniversary of the Internet," the name "Internet Supercomputer Conference" and the word "replenished." The anniversary dates the Internet from 1977, the name adds a word that the source does not print, and the source records an attempt and not a completed act. This is a definitional disagreement under D1 and two documentary findings.

8.3 Don Nielson writes that "the next call came from The Computer Museum History Center (now the Computer History Museum) about celebrating the 20th anniversary of the Internet at the Supercomputer Conference in San Jose in 1997." He writes that he and Don Alves of SRI began "trying to replenish the almost non-existent radio and internet equipment that had been in it, getting it re-licensed, and coaxing it to San Jose." The anniversary of 1997 is the anniversary that The Computer Museum History Center proposed, and it counts the Internet from the transmission of November 22, 1977, which under D1 was a transmission across research intranets, as section 3.0 records. Governing Definitions, D1.

8.4 This section records a definitional disagreement and two documentary findings and does not count lines 18 and 19 among the false-as-written verdicts. Line 18 accurately reports that a celebration of the 20th anniversary of the Internet was planned, and the disagreement lies in the anniversary itself.

8.5 Corrected statement: The van stood unused for about ten years on the back lot of SRI International until The Computer Museum History Center, now the Computer History Museum, proposed to show it at the Supercomputer Conference in San Jose, California, in 1997, in a celebration that the museum called the 20th anniversary of the Internet. Don Alves and Don Nielson of SRI International got the van running, tried to replenish its almost non-existent radio and network equipment, had it re-licensed and brought it to San Jose.

9.0 Line 22 says that the Computer History Museum presented a celebration of the 30th anniversary in 2007, which the museum's own press release supports, but the source that line 22 cites is dated 17 November 1977 and its address now leads to a page that does not mention the celebration, which is a documentary finding on the article's sourcing.

9.1 Line 22 of the article says: "In 2007, the Computer History Museum presented a 30th anniversary celebration of this demonstration, which included several participants of the 1977 event." The line cites the source at line 31, SRI International's "Timeline of innovations: Internetworking: The First Three-Network Transmission," which line 31 dates "17 November 1977."

9.2 Mark Nichols records the citation as a finding. A source dated 17 November 1977 cannot record a celebration of 2007, and the address that line 31 gives led on November 12, 2026 to SRI International's page "Internetworking," which does not mention the celebration. This is a documentary finding on the article's sourcing.

9.3 The Computer History Museum's press release of November 1, 2007 says: "On November 7, the Computer History Museum and the Web History Center will present a special celebration of an historic demonstration that led to the Internet we know and use today." It lists seven participants of the event of 1977 on the panel: Vinton Cerf of DARPA, Jim Garrett of Collins Radio Company, Irwin Jacobs of Linkabit, Robert Kahn of DARPA, Donald Nielson of SRI International, Paal Spilling of the Norwegian Defense Research Establishment and Virginia Strazisar Travers of BBN. The press release supports line 22, and the source that line 22 cites does not.

9.4 This section records a documentary finding on the sourcing of line 22 and does not count line 22 among the false-as-written verdicts.

9.5 Corrected statement: On November 7, 2007, the Computer History Museum and the Web History Center presented a celebration of the 30th anniversary of the transmission of November 22, 1977, with a panel of seven of its participants, as the Computer History Museum's press release of November 1, 2007 records.

10.0 The article states several things correctly that this page checked, and the documents that support each one are named here.

10.1 Line 4 says that DARPA's PRNET project "developed the world's first mobile ad hoc network." The line is supported at the scope of the documents. Don Nielson writes of the packet radio network: "It was the first mobile packet network," and he calls it "a self-organizing network, with addressing and routing." SRI International calls it "the world’s first mobile digital radio network." The words "ad hoc" do not appear in the sources this page read.

10.2 Line 5 says that the van "was a mobile packet radio laboratory that housed one of the PRNET radio nodes, to simulate the needs of in-the-field military to connect to the network." The line is supported. Don Nielson calls the van "an SRI outfitted mobile radio lab," and he writes that "internetworking was born of necessity, to demonstrate at ARPA that the innovations of packet switching were indeed relevant to the military's mode of operation."

10.3 Line 8 says that the van "resembled a bread van" and carried a Digital Equipment Corporation LSI-11. Those words are supported. Don Nielson calls the van SRI's "bread truck," and SRI International's page "Internetworking" shows "an LSI-11 minicomputer containing TCP plus terminal interfaces and a DataMedia terminal." Section 4.0 records the words "an ARPANET node via packet radio" in the same line as false as written.

10.4 Line 11 and line 12 give the date of August 27, 1976, the courtyard and the reason for the place. The date and the reason are supported. Don Nielson writes that the place "was far enough from SRI (Stanford Research Institute) to qualify as "remote," but close enough to have good radio contact with them through a repeater station atop a hill above Stanford," and that "No one would mind if we parked SRI's "bread truck" van alongside the courtyard and ran a few wires to one of the tables." The transcription of Don Nielson's article spells the name of the place "Rossetti's," and this page did not read the sources that line 11 cites for the name "Rossotti's" and for "Alpine Inn." Section 5.0 records the name "TCP/IP" in line 11 as false as written.

10.5 Line 13 says that on November 22, 1977 "SRI originated the first connection between three disparate networks." That clause is supported. SRI International says: "Then in 1977, the first connection was made across three dissimilar networks." Section 3.0 records the words "The first true Internet transmission" in the same line as false as written.

10.6 Line 16 says that the speech experiments "focused on how to compress speech such that it still sounded "natural" and arrived in a timely manner." The line is supported. Don Nielson writes that "transporting natural-sounding speech focused on the importance of delay variance."

10.7 Line 20 and line 21 say that the van was exhibited on the convention floor and that SRI donated it to the Computer History Museum to prevent further deterioration. The lines are supported. Don Nielson writes that the van "did seem to carry some symbolism for many who saw it," and that "rather than returning it to certain deterioration and scrap, SRI offered it to the Museum, where it lives today."

10.8 This page did not check line 3's statement that Don Cone refitted the van, line 8's statement that Don Cone designed it, line 9, or line 10, because the sources that the article cites for them, at lines 26 and 27, were not read, as 0.2 records.

10.9 Section 10.0 credits line 4 at the scope stated in 10.1, line 5, the words of line 8 stated in 10.3, the date and the reason of lines 11 and 12, the clause of line 13 stated in 10.5, line 16, line 20 and line 21 as supported, and section 9.3 credits line 22 as supported by a source that the article does not cite.

11.0 Six statements of the Wikipedia article Packet Radio Van are false as written, four further findings record a definitional disagreement, a documentary finding on the route, a definitional disagreement with two documentary findings on the van's return, and a documentary finding on a citation, and the article is not carried on marknichols.com as an authority on the birth of the Internet.

11.1 The following six statements of revision 1383611727 are false as written under F56. Each is decided by the dated documents named in the section cited.

Line 6 describes internetworking as "connecting different communications protocols via the Internet protocol suite," while Don Nielson writes that the protocol "was designed to carry information over dissimilar networks," and IP was first proposed as a separate protocol on August 15, 1977, as section 2.0 records.
Line 7 calls a demonstration between research intranets "the very first demonstration of the Internet," while the source it cites calls the event of 1976 "a two-network internet connection," as section 3.0 records.
Line 13 calls the transmission of November 22, 1977 "The first true Internet transmission," while the article's own line 3 and its own principal source place the first internetworked transmission on August 27, 1976, and the three networks of 1977 were government-sponsored research intranets, as section 3.0 records.
Line 8 calls the van "an ARPANET node via packet radio," while the source it cites calls the van "a portable node on the emerging Packet Radio Network (PRNET)," as section 4.0 records.
Line 11 calls the transmission of August 27, 1976 "The first two-network TCP/IP transmission," while Don Nielson records it as "the first formal use of the internet protocol known as "TCP,"" as section 5.0 records.
Line 15 calls the van "the site of the first experiments" with "Voice over IP," while the source its paragraph cites records that packet speech was first tried over the ARPANET and that the speech work influenced the separation of IP, as section 7.0 records.

11.2 Four further findings record disagreements that are not counted among the false-as-written verdicts.

Line 3 reports that the transmission of 1977 "is considered the start of the Internet" without naming who considers it so, which is a definitional disagreement under D1, as section 1.0 records.
Line 14 describes the route as "through the mobile van at SRI in Menlo Park," which departs from the Computer History Museum's sentence that it follows and leaves out the gateways and the host, which is a documentary finding, as section 6.0 records.
Lines 18 and 19 count the Internet from 1977, add the word "Internet" to the name of the Supercomputer Conference, and turn an attempt to replenish the van's equipment into a completed act, which is a definitional disagreement and two documentary findings, as section 8.0 records.
Line 22 cites, for a celebration of 2007, a source dated 17 November 1977, which is a documentary finding on the article's sourcing, as section 9.0 records.

11.3 The article answers its own claims in its own text and in its own sources.

Line 3 calls the transmission of August 27, 1976 "the first two-way internetworked transmission," and line 13 calls the transmission of November 22, 1977 "The first true Internet transmission," as section 3.0 records.
Line 5 says that the van "housed one of the PRNET radio nodes," and line 8 says that it contained the equipment "to be an ARPANET node," as section 4.0 records.
Line 15 credits "Voice over IP" to the van, and the source that its paragraph cites records that the speech work in the van helped bring the separate IP into being, as section 7.0 records.

11.4 Under D12, contemporaneous primary documents control over retrospective accounts, and this page has decided each disagreement by the following documents and accounts.

IEN 2 of August 15, 1977, by Jon Postel, first proposed "a new distinct internetwork protocol."
SRI International's "Progress Report on Packet Radio Experimental Network" of February 1978, by R. C. Kunzelman, V. D. Cone, K. S. Klemba, J. E. Mathis, J. L. McClurg and D. L. Nielson, traces the route of November 22, 1977 in its operating figure, as section 5.0 of the page on Vint Cerf's "Internet ca 1977" records.
Don Nielson's "The SRI Van and Computer Internetworking," published in CORE, Vol. 3, No. 1, by the Computer History Museum in February 2002, is the account of the principal investigator of SRI International for the packet radio program, and the article cites it six times.
The Computer History Museum's press release of November 1, 2007 lists the participants and the co-sponsors of the celebration of November 7, 2007.
CNET's article of November 8, 2007, by Erica Ogg, is the source of the paragraph of line 13 and line 14.
SRI International's page "Internetworking," read on November 12, 2026, is the institutional account of the builder of the van.

The article is a retrospective account with no author of record, its claim that the transmission of 1977 is "the start of the Internet" rests on one source that this page could not read and names no one who holds the view, and six of its statements are contradicted by the sources that the article itself cites or by the article's own lines. No line of it is carried on marknichols.com as controlling. Governing Definitions, D12.

11.5 The findings on this page are open to challenge on the terms stated at F40 of The Governing Definitions and Controlling Facts of Telecommunications Internetworking. A challenger who holds that a finding on this page is wrong states the competing claim in one sentence, names the document that carries it and the document's date, and submits both as F40 directs. A challenge submitted with its document is answered on this page, and a challenge submitted without a document is an opinion and is heard as one.

12.0 This section holds Exhibit A, the numbered text of the Wikipedia article Packet Radio Van in revision 1383611727 of November 3, 2026.

12.1 Exhibit A reproduces the text of revision 1383611727 line by line, under the names of the article's own sections, so that every line number cited on this page can be read in place.

Short description

1. Testbed for ARPANET internetworking

Image caption

2. SRI's Packet Radio Van

Lead

3. The Packet Radio Van was a GMC Value-Van refitted by Don Cone at SRI International, and equipped with technology that was used in the first two-way internetworked transmission on August 27, 1976, and the first three-way internetworked transmission on November 22, 1977, the latter of which is considered the start of the Internet.

Background

4. The van was created as part of DARPA's PRNET project, which developed the world's first mobile ad hoc network.

5. It was a mobile packet radio laboratory that housed one of the PRNET radio nodes, to simulate the needs of in-the-field military to connect to the network.

6. As DARPA further wished to connect the disparate computers at its various contractors, and indeed globally, there was a push to test internetworking - connecting different communications protocols via the Internet protocol suite.

7. The van played a unique role in the very first demonstration of the Internet.

Equipment

8. The GMC van, designed by Don Cone, resembled a bread van and contained all of the equipment needed to be an ARPANET node via packet radio, including a Digital Equipment Corporation DEC LSI-11 16-bit minicomputer.

9. Other equipment included a shielded generator, flexible equipment racks, and air conditioning.

10. Due to his contributions around that time, Cone was promoted to Research Engineer.

Transmissions

11. The first two-network TCP/IP transmission was between the van and ARPANET on August 27, 1976; the van was parked next to Rossotti's (since 1956, officially the "Alpine Inn"), a well-known Portola Valley, California biker bar, and wires were run to one of the picnic tables.

12. The location was chosen as to be far enough from SRI in Menlo Park, California to be "remote" but close enough to have good radio contact.

13. The first true Internet transmission occurred on November 22, 1977, when SRI originated the first connection between three disparate networks.

14. Data flowed seamlessly through the mobile van at SRI in Menlo Park, California and the University of Southern California in Los Angeles via London, England, across three types of networks: packet radio, satellite, and the ARPANET.

15. The van was also the site of the first experiments (primarily by Earl Craighill and Tom Magill) with Voice over IP through ARPA's Network Speech Compression Program around 1977 to 1978.

16. They focused on how to compress speech such that it still sounded "natural" and arrived in a timely manner.

17. The phone in the van was a Mickey Mouse phone.

Legacy

18. The van was parked unused for a decade in a back lot of the SRI campus until the planning of a celebration of the 20th anniversary of the Internet in 1997 at the Internet Supercomputer Conference in San Jose, California.

19. SRI employees Don Alves and Don Nielson cleaned, licensed, and replenished the van's radio and Internet equipment.

20. The van was exhibited on the convention floor and was popular with attendees.

21. SRI donated the van to the Computer History Museum to prevent further deterioration.

22. In 2007, the Computer History Museum presented a 30th anniversary celebration of this demonstration, which included several participants of the 1977 event.
