It was planned to launch on February 21, 1967, as the first [[low Earth orbit]]al test of the [[Apollo command and service module]]. The mission never flew; a cabin fire during a launch rehearsal test at [[Cape Canaveral Air Force Station Launch Complex 34|Cape Kennedy Air Force Station Launch Complex 34]] on January 27 killed all three crew members—Command Pilot [[Gus Grissom]], Senior Pilot [[Ed White (astronaut)|Ed White]], and Pilot [[Roger B. Chaffee]]—and destroyed the command module (CM). The name Apollo 1, chosen by the crew, was made official by [[NASA]] in their honor after the fire. Immediately after the fire, NASA convened an Accident Review Board to determine the cause of the fire, and both chambers of the [[United States Congress]] conducted their own [[United States congressional hearing|committee inquiries]] to oversee NASA's investigation. The ignition source of the fire was determined to be electrical, and the fire spread rapidly due to combustible nylon material and the high-pressure pure oxygen cabin atmosphere. Rescue was prevented by the [[plug door]] hatch, which could not be opened against the internal pressure of the cabin. Because the rocket was unfueled, the test had not been considered hazardous, and emergency preparedness for it was poor. During the Congressional investigation, Senator [[Walter Mondale]] publicly revealed a NASA internal document citing problems with prime Apollo contractor [[North American Aviation]], which became known as the [[Phillips Report]]. This disclosure embarrassed NASA Administrator [[James E. Webb]], who was unaware of the document's existence, and attracted controversy to the Apollo program. Despite congressional displeasure at NASA's lack of openness, both congressional committees ruled that the issues raised in the report had no bearing on the accident. Crewed Apollo flights were suspended for twenty months while the command module's hazards were addressed. However, the development and uncrewed testing of the [[lunar module]] (LM) and [[Saturn V]] rocket continued. The [[Saturn IB]] launch vehicle for Apollo{{nbsp}}1, AS-204, was used for the first LM test flight, [[Apollo 5]]. The first successful crewed Apollo mission was flown by Apollo{{nbsp}}1's backup crew on [[Apollo 7]] in October 1968. == Crew == {{Spaceflight crew |terminology = Astronaut |position1 = Command Pilot |crew1_up = [[Gus Grissom]] |flights1_up = Would have been third |position2 = Senior Pilot |crew2_up = [[Ed White (astronaut)|Edward H.

In a spacecraft review meeting held with Shea on August 19, 1966 (a week before delivery), the crew expressed concern about the amount of flammable material (mainly nylon netting and [[hook and loop fastener|Velcro]]) in the cabin, which both astronauts and technicians found convenient for holding tools and equipment in place. Although Shea gave the spacecraft a passing grade, after the meeting they gave him a crew portrait they had posed with heads bowed and hands clasped in prayer, with the inscription: {{Blockquote|It isn't that we don't trust you, Joe, but this time we've decided to go over your head.<ref name="murray">{{Cite book |last1=Murray |first1=Charles |title=Apollo: The Race to the Moon |last2=Cox |first2=Catherine Bly |publisher=Simon & Schuster |year=1990 |isbn=978-0-671-70625-8 |location=New York |ref=Murray & Cox |author-link=Charles Murray (political scientist)}}</ref>{{rp|184}}}} Shea gave his staff orders to tell North American to remove the flammables from the cabin, but did not supervise the issue personally.<ref name="murray" />{{rp|185}} North American shipped spacecraft CM-012 to Kennedy Space Center on August 26, 1966, under a conditional Certificate of Flight Worthiness: 113 significant incomplete planned engineering changes had to be completed at KSC.

Altitude testing was performed first uncrewed, then with both the prime and backup crews, from October 10 through December 30. During this testing, the environmental control unit in the command module was found to have a design flaw, and was sent back to the manufacturer for design changes and rework. The returned ECU then leaked water/glycol coolant, and had to be returned a second time. Also during this time, a propellant tank in another service module had ruptured during testing at NAA, prompting the removal from the KSC test chamber of the service module so it could be tested for signs of the tank problem. These tests were negative. In December the second Block I flight AS-205 was canceled as unnecessary; Schirra, Eisele and Cunningham were reassigned as the backup crew for Apollo{{nbsp}}1. McDivitt's crew was now promoted to prime crew of the Block II/LM mission, re-designated AS-258 because the AS-205 launch vehicle would be used in place of AS-207.

Passing this test was essential to making the February 21 launch date. The test was considered non-hazardous because neither the launch vehicle nor the spacecraft was loaded with fuel or [[cryogenics]] and all [[pyrotechnic fastener|pyrotechnic]] systems (explosive bolts) were disabled.<ref name="SP4029" /> At 1:00&nbsp;pm [[Eastern Time Zone|EST]] (18:00 [[Greenwich Mean Time|GMT]]) on January 27, first Grissom, then Chaffee, and White entered the command module fully pressure-suited, and were strapped into their seats and hooked up to the spacecraft's oxygen and communication systems. Grissom immediately noticed a strange odor in the air circulating through his suit which he compared to "sour buttermilk", and the simulated countdown was put on hold at 1:20&nbsp;pm, while air samples were taken. No cause of the odour could be found, and the countdown was resumed at 2:42&nbsp;pm. The accident investigation found this odour not to be related to the fire.<ref name="SP4029" /> Three minutes after the count was resumed the hatch installation was started. The hatch consisted of three parts: a removable inner hatch which stayed inside the cabin; a hinged outer hatch which was part of the spacecraft's heat shield; and an outer hatch cover which was part of the boost protective cover enveloping the entire command module to protect it from aerodynamic heating during launch and from launch escape rocket exhaust in the event of a launch abort. The boost hatch cover was partially, but not fully, latched in place because the flexible boost protective cover was slightly distorted by some cabling run under it to provide the simulated internal power (the spacecraft's fuel cell reactants were not loaded for this test). After the hatches were sealed, the air in the cabin was replaced with pure oxygen at {{convert|16.7|psi|kPa|abbr=on|lk=on}}, {{convert|2|psi|kPa|abbr=on}} higher than atmospheric pressure.<ref name="SP4029" /><ref name="aibreport" />{{rp|Enclosure V-21|p=181}} Movement by the astronauts was detected by the spacecraft's [[inertial measurement unit]] and the astronauts' biomedical sensors, and also indicated by increases in oxygen spacesuit flow, and sounds from Grissom's stuck-open microphone. The stuck microphone was part of a problem with the communications loop connecting the crew, the [[Operations and Checkout Building]], and the Complex 34 blockhouse control room. The poor communications led Grissom to remark: "How are we going to get to the Moon if we can't talk between two or three buildings?" The simulated countdown was put on hold again at 5:40&nbsp;pm while attempts were made to troubleshoot the communications problem. All countdown functions up to the simulated internal power transfer had been successfully completed by 6:20&nbsp;pm, and at 6:30 the count remained on hold at T minus 10 minutes.<ref name="SP4029" /> === The fire === [[File:Apollo 1's Command Module - GPN-2003-00057.jpg|thumb|upright|Command module exterior, blackened from the eruption of fire]] [[File:Apollo One Recording.ogg|thumb|Audio recording from the ground loop, starting from Grissom's "talk between buildings" remark. The first mention of fire is heard at 1:05.]] The crew members were using the time to run through their checklist again, when a momentary increase in AC Bus{{nbsp}}2 voltage occurred. Nine seconds later (at 6:31:04.7), one of the astronauts (some listeners and laboratory analysis indicate Grissom) exclaimed "Hey!", "Fire!",<ref name="aibreport" />{{rp|5–8}} or "Flame!";<ref>{{Cite book |last=Slade |first=Suzanne |title=Countdown: 2979 Days to the Moon |publisher=Peachtree |others=Illustrated by Thomas Gonzalez |year=2018 |isbn=978-1-68263-013-6 |location=Atlanta |page=18}}</ref> this was followed by two seconds of scuffling sounds through Grissom's open microphone. This was immediately followed at 6:31:06.2 (23:31:06.2 GMT) by someone (believed by most listeners, and supported by laboratory analysis, to be Chaffee) saying, "[I've, or We've] got a fire in the cockpit." After 6.8 seconds of silence, a second, badly garbled transmission was heard by various listeners (who believed this transmission was made by Chaffee<ref name="aibreport" />{{rp|5–9}}) as: * "They're fighting a bad fire—Let's get out{{nbsp}}... Open 'er up", * "We've got a bad fire—Let's get out{{nbsp}}... We're burning up", or * "I'm reporting a bad fire{{nbsp}}... I'm getting out{{nbsp}}..." The transmission lasted 5.0 seconds and ended with a cry of pain.<ref name="aibreport" />{{rp|5-8, 5-9}} Some blockhouse witnesses said that they saw White on the television monitors, reaching for the inner hatch release handle<ref name="SP4029" /> as flames in the cabin spread from left to right.<ref name="aibreport" />{{rp|5-3}} The heat of the fire fed by pure oxygen caused the pressure to rise to {{convert|29|psi|kPa|abbr=on}}, which ruptured the command module's inner wall at 6:31:19 (23:31:19 GMT, initial phase of the fire). Flames and gases then rushed outside the command module through open access panels to two levels of the pad service structure. The intense heat, dense smoke, and ineffective gas masks designed for toxic fumes rather than smoke, hampered the ground crew's attempts to rescue the men. There were fears the command module had exploded, or soon would, and that the fire might ignite the solid fuel rocket in the launch escape tower above the command module, which would have likely killed nearby ground personnel, and possibly have destroyed the pad.<ref name="SP4029" /> As the pressure was released by the cabin rupture, the rush of gases within the module caused flames to spread across the cabin, beginning the second phase. The third phase began when most of the oxygen was consumed and was replaced with atmospheric air, essentially quenching the fire, but causing high concentrations of carbon monoxide and heavy smoke to fill the cabin, and large amounts of soot to be deposited on surfaces as they cooled.<ref name="SP4029" /><ref name="aibreport" />{{rp|5-3, 5-4}} It took five minutes for the pad workers to open all three hatch layers, and they could not drop the inner hatch to the cabin floor as intended, so they pushed it out of the way to one side. Although the cabin lights remained on, they were unable to see the astronauts through the dense smoke. As the smoke cleared they found the bodies, but were not able to remove them. The fire had partly melted Grissom's and White's nylon space suits and the hoses connecting them to the life support system. Grissom had removed his restraints and was lying on the floor of the spacecraft. White's restraints were burned through, and he was found lying sideways just below the hatch. It was determined that he had tried to open the hatch per the emergency procedure, but was not able to do so against the internal pressure. Chaffee was found strapped into his right-hand seat, as procedure called for him to maintain communication until White opened the hatch. Because of the large strands of melted nylon fusing the astronauts to the cabin interior, removing the bodies took nearly 90 minutes. The bodies were only able to be removed after 7.5 hours from the time the incident took place, due to the gasses and toxins present which prevented medical personnel from entering initially.<ref name="SP4029" /> Deke Slayton was possibly the first NASA official to examine the spacecraft's interior.<ref name="Leopold">{{Cite book |last=Leopold |first=George |title=Calculated Risk: The Supersonic Life and Times of Gus Grissom |publisher=[[Purdue University Press]] |year=2016 |isbn=978-1-55753-745-4 |location=West Lafayette, Indiana |pages=259–260}}</ref> His testimony contradicted the official report concerning the position of Grissom's body. Slayton said of Grissom and White's bodies, "it is very difficult for me to determine the exact relationships of these two bodies. They were sort of jumbled together, and I couldn't really tell which head even belonged to which body at that point.

Chaffee suffered third-degree burns on almost a quarter of his body and a small portion of his spacesuit was damaged. The autopsy report determined that the primary cause of death for all three astronauts was [[cardiac arrest]] caused by high concentrations of [[carbon monoxide]]. Burns suffered by the crew were not believed to be major factors, and it was concluded that most of them had occurred postmortem. [[Asphyxiation]] occurred after the fire melted the astronauts' suits and oxygen tubes, exposing them to the lethal atmosphere of the cabin.<ref name="aibreport" />{{rp|6-1}} === Major causes of accident === The review board identified several major factors which combined to cause the fire and the astronauts' deaths:<ref name="SP4029" /> * An ignition source most probably related to "vulnerable wiring carrying spacecraft power" and "vulnerable plumbing carrying a combustible and corrosive coolant" * A pure oxygen atmosphere at higher than atmospheric pressure * A cabin sealed with a hatch cover which could not be quickly removed at high pressure * An extensive distribution of combustible materials in the cabin * Inadequate emergency preparedness (rescue or medical assistance, and crew escape) ==== Ignition source ==== The review board determined that the electrical power momentarily failed at 23:30:55 GMT, and found evidence of several [[electric arc]]s in the interior equipment. They were unable to conclusively identify a single ignition source. They determined that the fire most likely started near the floor in the lower left section of the cabin, close to the Environmental Control Unit.<ref name="aibreport" />{{rp|6-1}} It spread from the left wall of the cabin to the right, with the floor being affected only briefly.<ref name="aibreport" />{{rp|5-3}} The board noted that a silver-plated copper wire, running through an environmental control unit near the center couch, had become stripped of its [[Polytetrafluoroethylene|Teflon]] insulation and abraded by repeated opening and closing of a small access door.{{efn|In 1967 a vice president of North American Aviation, John McCarthy, speculated that Grissom had accidentally "scuffed the insulation of a wire" while moving about the spacecraft, but his remarks were ignored by the review board and strongly rejected by a congressional committee. [[Frank Borman]], who had been the first astronaut to go inside the burned spacecraft, testified, "We found no evidence to support the thesis that Gus, or any of the crew members kicked the wire that ignited the flammables." A 1978 history of the accident written internally by NASA said at the time, "This theory that a scuffed wire caused the spark that led to the fire still has wide currency at Kennedy Space Center.

Experiments at the [[Illinois Institute of Technology]] confirmed the hazard existed for silver-plated wires, but not for copper-only or nickel-plated copper.

A third outer layer, the boost protective hatch cover, is not shown.]] The inner hatch cover used a [[plug door]] design, sealed by higher pressure inside the cabin than outside. The normal pressure level used for launch ({{convert|2|psi|kPa|abbr=on}} above ambient) created sufficient force to prevent removing the cover until the excess pressure was vented. Emergency procedure called for Grissom to open the cabin vent valve first, allowing White to remove the cover,<ref name="SP4029" /> but Grissom was prevented from doing this because the valve was located to the left, behind the initial wall of flames. Also, while the system could easily vent the normal pressure, its flow capacity was utterly incapable of handling the rapid increase to {{convert|29|psi|kPa|abbr=on}} caused by the intense heat of the fire.<ref name="aibreport" />{{rp|5-3}} North American had originally suggested the hatch open outward and use [[explosive bolt]]s to blow the hatch in case of emergency, as had been done in [[Project Mercury]]. NASA did not agree, arguing the hatch could accidentally open, as it had on Grissom's ''[[Mercury-Redstone 4#Liberty Bell 7|Liberty Bell 7]]'' flight, so the [[Lyndon B.

According to [[Deke Slayton|Donald K.

First, a pure oxygen atmosphere is comfortably breathable by humans at {{convert|5|psi|kPa|abbr=on}}, greatly reducing the pressure load on the spacecraft in the vacuum of space. Second, nitrogen used with the in-flight pressure reduction carried the risk of [[decompression sickness]] (known as "the bends"). But the decision to eliminate the use of any gas but oxygen was criticized when a serious accident occurred on April 21, 1960, in which [[McDonnell Aircraft]] test pilot G. B. North passed out and was seriously injured when testing a Mercury cabin / spacesuit atmosphere system in a vacuum chamber. The problem was found to be nitrogen-rich (oxygen-poor) air leaking from the cabin into his spacesuit feed.<ref>{{Cite journal |last=Giblin |first=Kelly A. |date=Spring 1998 |title=Fire in the Cockpit! |url=http://www.americanheritage.com/articles/magazine/it/1998/4/1998_4_46.shtml |journal=[[American Heritage of Invention & Technology]] |publisher=American Heritage Publishing |volume=13 |issue=4 |archive-url=https://web.archive.org/web/20081120153024/http://www.americanheritage.com/articles/magazine/it/1998/4/1998_4_46.shtml |archive-date=November 20, 2008 |access-date=March 23, 2011}}</ref> North American Aviation had suggested using an oxygen/nitrogen mixture for Apollo, but NASA overruled this.

The Senate committee noted in its final report NASA's testimony that "the findings of the [Phillips] task force had no effect on the accident, did not lead to the accident, and were not related to the accident",<ref name="anderson">{{Cite book |last=Anderson |first=Clinton P. |url=http://klabs.org/richcontent/Reports/Failure_Reports/as-204/senate_956/index.htm |title=Apollo 204 Accident: Report of the Committee on Aeronautical and Space Sciences, United States Senate, with Additional Views |date=January 30, 1968 |publisher=U.S. Government Printing Office |volume=Senate Report 956 |location=Washington, D.C. |ref=Anderson |author-link=Clinton Presba Anderson |archive-url=https://web.archive.org/web/20141220043317/http://klabs.org/richcontent/Reports/Failure_Reports/as-204/senate_956/index.htm |archive-date=December 20, 2014}}</ref>{{rp|7}} but stated in its recommendations: {{Blockquote|Notwithstanding that in NASA's judgment the contractor later made significant progress in overcoming the problems, the committee believes it should have been informed of the situation.

Brooke III]] and [[Charles H. Percy]] jointly wrote an ''Additional Views'' section appended to the committee report, chastising NASA more strongly than Anderson for not having disclosed the Phillips review to Congress. Mondale wrote his own, even more strongly worded Additional View, accusing NASA of "evasiveness,{{nbsp}}... lack of candor,{{nbsp}}... patronizing attitude toward Congress{{nbsp}}... refusal to respond fully and forthrightly to legitimate Congressional inquiries, and{{nbsp}}... solicitous concern for corporate sensitivities at a time of national tragedy".<ref name="anderson" />{{rp|16}} The potential political threat to Apollo blew over, due in large part to the support of President Lyndon B. Johnson, who at the time still wielded a measure of influence with the Congress from his own Senatorial experience. He was a staunch supporter of NASA since its inception, had even recommended the Moon program to President [[John F. Kennedy]] in 1961, and was skilled at portraying it as part of Kennedy's legacy. Relations between NASA and North American deteriorated over the assignment of blame. North American argued unsuccessfully it was not responsible for the fatal error in spacecraft atmosphere design. Finally, Webb contacted Atwood, and demanded either he or Chief Engineer [[Harrison Storms|Harrison A. Storms]] resign. Atwood elected to fire Storms.<ref>{{Cite episode |title=The Other Side of the Moon |series=Project Apollo |last=Burke |first=James (presenter) |author-link=James Burke (science historian) |network=[[BBC]] |number=2 |last2=Low |first2=George |author-link2=George Low |last3=Myers |first3=Dale D. |author-link3=Dale D.

The command module was found to be extremely hazardous and, in some instances, carelessly assembled (for example, a misplaced wrench socket was found in the cabin).<ref name="aibreport" />{{rp|5–10}} It was decided that the remaining Block I spacecraft would be used only for uncrewed Saturn V test flights. All crewed missions would use the [[Apollo command and service module#Major differences between Block I and Block II|Block II spacecraft]], to which many command module design changes were made: * The cabin atmosphere at launch was adjusted to 60% oxygen and 40% nitrogen at sea-level pressure: {{convert|14.7|psi|kPa|abbr=on}}. During ascent the cabin rapidly vented down to {{convert|5|psi|kPa|abbr=on}}, releasing approximately 2/3 of the gas originally present at launch. The vent then closed and the environmental control system maintained a nominal cabin pressure of {{convert|5|psi|kPa|abbr=on}} as the spacecraft continued into vacuum. The cabin was then very slowly purged (vented to space and simultaneously replaced with 100% oxygen), so the nitrogen concentration gradually fell off to zero over the next day. Although the new cabin launch atmosphere was significantly safer than 100% oxygen, it still contained almost three times the amount of oxygen present in ordinary sea-level air (20.9% oxygen). This was necessary to ensure a sufficient [[partial pressure]] of oxygen when the astronauts removed their helmets after reaching orbit. (60% of five psi is three psi, compared to 60% of {{convert|14.7|psi|kPa|abbr=on}} which is {{convert|8.8|psi|kPa|abbr=on}} at launch, and 20.9% of {{convert|14.7|psi|kPa|abbr=on}} which is {{convert|3.07|psi|kPa|abbr=on}} in sea-level air.)<ref name="chariot" /> * The environment within the astronauts' pressure suits was not changed. Because of the rapid drop in cabin (and suit) pressures during ascent, [[decompression sickness]] was likely unless the nitrogen had been purged from the astronauts' tissues before launch. They would still breathe pure oxygen, starting several hours before launch, until they removed their helmets on orbit. Avoiding the "bends" was considered worth the residual risk of an oxygen-accelerated fire within a suit.<ref name="chariot" /> * Nylon used in the [[Gemini space suit|Block I suits]] was replaced in the [[Apollo/Skylab A7L|Block II suits]] with [[Beta cloth]], a non-flammable, highly melt-resistant fabric woven from [[Glass (fiber)|fiberglass]] and coated with Teflon.<ref name="chariot">{{Cite web |last1=Brooks |first1=Courtney |last2=Grimwood |first2=James |last3=Swenson |first3=Loyd |date=1979 |title=The Slow Recovery |url=http://www.hq.nasa.gov/office/pao/History/SP-4205/ch9-4.html |access-date=May 14, 2016 |publisher=NASA}}</ref> * Block II had already been planned to use a completely redesigned hatch which opened outward, and could be opened in less than five seconds.<ref name="chariot" /> Concerns of accidental opening were addressed by using a cartridge of pressurized nitrogen to drive the release mechanism in an emergency, instead of the [[explosive bolt]]s used on Project Mercury. * Flammable materials in the cabin were replaced with self-extinguishing versions. * Plumbing and wiring were covered with protective [[thermal insulation|insulation]].
