The planned low Earth orbital test of the Apollo Command/Service Module, never made its target launch date of February 21, 1967, because a cabin fire during a launch rehearsal test on January 27 at Cape Canaveral Air Force Station Launch Complex 34 killed all three crew members—Command Pilot Virgil I. "Gus" Grissom, Senior Pilot Edward H. White II and Pilot Roger B. Chaffee—and destroyed the Command Module (CM). The name Apollo 1, chosen by the crew, was officially retired by NASA in commemoration of them on April 24, 1967. Immediately after the fire, NASA convened the Apollo 204 Accident Review Board to determine the cause of the fire, and both houses of the United States Congress launched their own committee inquiries to oversee NASA's investigation... Although the ignition source could not be conclusively identified, the astronauts' deaths were attributed to a wide range of lethal design and construction flaws in the early Apollo Command Module. Manned Apollo flights were suspended for 20 months while these problems were corrected... AS-204 was to be the first manned test flight of the Apollo Command/Service Module (CSM) to Earth orbit... The launch simulation on January 27, 1967, was a "plugs-out" test to determine whether the spacecraft would operate nominally on (simulated) internal power while detached from all cables and umbilicals... The crew members were using the time to run through their checklist again, when a voltage transient was recorded at 6:30:54 (23:30:54 GMT). Ten seconds later (at 6:31:04), Chaffee exclaimed "Hey!", and scuffling sounds followed for two seconds. White then reported, "I've got a fire in the cockpit!". Some witnesses said that they saw White on the television monitors, reaching for the inner hatch release handle as flames in the cabin spread from left to right and licked the window. The final voice transmission is believed to have come from Chaffee. Six seconds after White's report of a "fire in the cockpit", a voice cried out, "There's a bad fire!". The sound of the spacecraft's hull rupturing was heard immediately afterwards, followed by "I'm burning up!" and a scream. The transmission then ended abruptly at 6:31:21, only 17 seconds after the first report of fire. The cabin had ruptured due to rapidly expanding gases from the fire, which over-pressurized the Command Module to 29 psi (2.0 bar). Flames and gases then rushed outside the Command Module through open access panels to two levels of the pad service structure. Intense heat, dense smoke, and ineffective gas masks designed for toxic fumes rather than heavy 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 rockets in the launch escape tower above the Command Module, which would have likely killed nearby ground personnel. It took five minutes 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. The initial phase of the fire lasted only about 15 seconds before the Command Module's hull ruptured. As the cabin depressurized, the convective rush of air caused the flames to spread rapidly, beginning the second phase. The third phase began when most of the atmosphere was consumed. At this point, the fire largely stopped, but massive amounts of smoke, dust, carbon monoxide, and fumes now filled the cabin... 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.
