Their mission, officially called Apollo 204 but better known as Apollo 1, was to be the first piloted Apollo flight. As they would on launch day, the astronauts and ground crews sealed the three hatches of the capsule and pressurized it with pure oxygen at 16.7 pounds per square inch (psi), slightly higher than atmospheric pressure. At 6:31 p.m., a flash fire broke out inside the cabin. Within seconds, rising temperatures and pressures caused the CM pressure vessel to crack, releasing flames and smoke onto the launch pad\u2019s service structure. The astronauts, in vain, attempted to open the inner hatch, while the pad crew valiantly worked to open the outer two hatches, their attempts hampered by dense smoke and heat. By the time they opened the hatches, the crew had already perished. Later that night, after photographers fully documented the scene, recovery crews removed the astronauts\u2019 bodies from the spacecraft and took them to a nearby medical facility. U.S. Air Force pathologists conducted examinations, concluding that the astronauts died of asphyxia from carbon monoxide and other toxic gases resulting from the fire. The burns they received were likely survivable.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" width=\"214\" height=\"170\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_4_as1-0329-67h-133-grissom_coffin_being_loaded_into_hearse_at_cape-1.30.67.jpg\" alt=\"grissom_coffin_being_loaded_into_hearse_at_cape-1.30.67\"> <img decoding=\"async\" loading=\"lazy\" width=\"217\" height=\"170\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_5_as1-0331a-noid-astronaut_coffins_being_loaded_onto_military_transport_at_cape-1.30.67.jpg\" alt=\"a-noid-astronaut_coffins_being_loaded_onto_military_transport_at_cape-1.30.67\"> <img decoding=\"async\" loading=\"lazy\" width=\"252\" height=\"170\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_6_as1-0332a-67h-141-grissom_funeral_procession_at_arlington_cemetary-2.1.67.jpg\" alt=\"grissom_funeral_procession_at_arlington_cemetary-2.1.67\"><br><em>Left: At NASA\u2019s Kennedy Space Center in Florida, soldiers load astronaut Virgil I. \u201cGus\u201d Grissom\u2019s coffin into a hearse.

Although they couldn\u2019t determine a specific source of ignition, investigators found evidence of arcing in several wires in the spacecraft underneath Grissom\u2019s left hand couch, near the environment control system. That area of the spacecraft received the most severe fire damage. Because of the pure oxygen atmosphere, pressurized to 16.7 psi \u2013 two pounds above atmospheric pressure and a larger-than-allowable amount of flammable material in the spacecraft \u2013 the fire spread very rapidly. The fire caused a rapid rise in temperature and pressure, resulting in the rupture of the CM pressure vessel and generating toxic chemicals such as carbon monoxide, leading to the death of the astronauts by asphyxiation. The design of the three-piece hatch, with the innermost one opening inward and taking 90 seconds to open under ideal conditions and impossible under the increased pressure, prevented the astronauts from exiting the spacecraft. Because the test took place with the rocket unfueled, it had been considered non-hazardous and was not reviewed by the relevant safety organizations. Therefore, no provisions were made for rescuing the astronauts or treating injured crew members or pad crew in case of an accident.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" width=\"281\" height=\"190\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_26_as1-0357-67p-162-borman_briefs_members_of_house_of_representatives_subcommittee-4.21.67-1.jpg\" alt=\"borman_briefs_members_of_house_of_representatives_subcommittee-4.21.67\"> <img decoding=\"async\" loading=\"lazy\" width=\"235\" height=\"190\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_27_senate_hearings_caption_in_draft_text-1.jpg\" alt=\"senate_hearings_caption_in_draft_text\"><br> <em>Left: Astronaut Frank Borman gives a tour of CM-012 to members of the House of Representatives subcommittee during their visit to NASA\u2019s Kennedy Space Center in Florida.

In the area of organizational changes, MSC Director Gilruth established a Safety, Reliability, and Quality Assurance Office, today known as the Safety and Mission Assurance Directorate, independent of the Apollo Spacecraft Program Office and reporting directly to the center director. At the agency level, NASA established the Aerospace Safety Advisory Panel (ASAP) for independent safety oversight. The ASAP is still active today.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" alt=\"demonstration_of_new_pump_handle_on_cm_hatch-6.14.67\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_32_as1-0359-67h-963-demonstration_of_new_pump_handle_on_cm_hatch-6.14.67.jpg\" width=\"222\" height=\"220\"> <img decoding=\"async\" loading=\"lazy\" alt=\"apollo_1_aftermath\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_33_19680904-01_68-hc-551.jpg\" width=\"293\" height=\"220\"><br>\n<em>Left: An early prototype of the unified Apollo hatch design.<br>\nRight: The unified hatch installed on the Apollo 7 spacecraft.<\/em><\/p>\n\n\n\n<p>Following the fire, NASA decided that all subsequent Apollo crews would fly aboard the more advanced Block II version of the spacecraft, not the Block I assigned to Apollo 1. Unlike the Block I version, Block II CM\u2019s included a docking probe and a transfer tunnel enabling docking with the LM and internal crew transfers between the two docked vehicles. The most significant hardware change to the Apollo spacecraft as a result of the fire involved replacing the difficult-to-open three-piece hatch with a unified hatch that could be opened from inside or outside the spacecraft in three seconds. NASA instituted a new approach to the selection and placement of materials, severely restricting and controlling the amount and location of combustible material in the spacecraft. Although the fire took place in the CM, NASA instituted these changes in the LM as well to reduce the risk of fire and to increase crew safety. NASA developed a new spacesuit that used fire resistant materials.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" width=\"517\" height=\"370\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_34_apollo_7_prime_and_backup_crew_conference_naa_may_10_1967.jpg\" alt=\"prime_and_backup_crew_conference_naa_may_10_1967\"><br> <em>Prime and backup crews for the first piloted Apollo mission at the May 10, 1967 news conference at North American Aviation\u2019s Downey, California, plant \u2013 Eugene A.

The next day, the six astronauts held a press conference in Downey, where they expressed satisfaction with the changes being made to make their spacecraft safe to fly. Specifically, they cited the new outward-opening unified hatch, removal or replacement of flammable materials, protection of wiring bundles, and flame-resistant spacesuits.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" width=\"220\" height=\"220\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_35_as1-0361-67h-1017651-apollo_204_cm_being_prepared_for_shipment_from_ksc_to_langley-7.6.67.jpg\" alt=\"apollo_204_cm_being_prepared_for_shipment_from_ksc_to_langley-7.6.67\"> <img decoding=\"async\" loading=\"lazy\" width=\"294\" height=\"220\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/02\/apollo_1_aftermath_36_hatch_at_ksc_apollo_saturn_v_center-1.png\" alt=\"hatch_at_ksc_apollo_saturn_v_center\"><br> <em>Left: Workers prepare the Apollo 1 spacecraft for shipment to NASA\u2019s Langley Research Center in Hampton, Virginia, for long-term storage.
