No cause of the odor could be found, and the countdown was resumed at 2:42 pm. The accident investigation found this odor not to be related to the fire. 11 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. 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.7 psi (115 kpa 2 psi (14 kPa) higher than atmospheric pressure. 11 not in citation given audio recording from the ground loop, starting from Grissom's "talk between buildings" remark. First mention of fire is heard at 1:05. Movement by the astronauts was detected by the spacecraft's inertial measurement unit and the astronaut's biomedical sensors, and also indicated by increases in oxygen spacesuit flow, and sounds from Grissom's stuck-open microphone.
You sort of have to put that out of your mind. There's always a possibility that you can have a catastrophic failure, of course; this can happen on any flight; it can happen on the last one as well as the first one. So, you just plan as best you can to take care of all these eventualities, and you get a well-trained crew and you go fly. — Gus Grissom, in a december 1966 interview 21 Accident edit Plugs-out test edit Chaffee, white, and Grissom training in a simulator of their Command Module cabin, january 19, 1967 The launch simulation on January 27, 1967, on pad 34, was a "plugs-out" test to determine. 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 systems (explosive bolts) were disabled. 11 At 1:00 pm est (1800 gmt ) help 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 held at 1:20 pm, while air samples were taken.
In December, the second Block i flight as-205 was canceled as unnecessary; and Schirra, eisele and Cunningham were reassigned as the backup crew for Apollo. 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. A third manned mission was planned to launch the csm and lm together on a saturn V (AS-503) to an elliptical medium Earth orbit (meo to be crewed by Frank borman, michael Collins and William Anders. Mcdivitt, Scott and Schweickart had started their training for as-258 in cm-101 at the naa plant in Downey, california, when the Apollo 1 accident occurred. 19 Once all outstanding csm-012 hardware problems were fixed, the reassembled spacecraft finally completed a successful altitude chamber test with Schirra's backup crew on December. 17 :42 According to the final report of the accident investigation board, "At the post-test debriefing the backup flight crew expressed their satisfaction with the condition and performance of the spacecraft." 17 :42 This would appear to contradict the account given in Lost moon. Something about it just doesn't ring right and that Grissom should get out at the first sign of trouble. 20 Following the successful altitude tests, the spacecraft was removed from the altitude chamber on January 3, 1967, and mated to its Saturn ib launch vehicle on pad 34 on January.

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 Velcro ) in the cabin, which both astronauts and technicians found convenient for holding tools. Though 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: It isn't that we don't trust you, joe, but this time we've decided. 16 :184 Shea gave his staff orders to tell North American to remove the flammables from the cabin, but did not supervise the issue personally. 16 :185 wallpaper 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. But that was paroles not all; an additional 623 engineering change orders were made and completed after delivery. 17 :63 Grissom became so frustrated with the inability of the training simulator engineers to keep up with the spacecraft changes, that he took a lemon from a tree by his house 18 and hung it on the simulator. 7 The command and Service modules were mated in the ksc altitude chamber in September, and combined system testing was performed.
Altitude testing was performed first unmanned, then with both the prime and backup crews, from October 10 through December. 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 Service module 017 had ruptured during testing at naa, prompting the separation of the modules and removal from the chamber so the service module could be tested for signs of the tank problem. These tests were negative. Mcdivitt, Scott and Schweickart were training for the second Apollo mission on January 26, 1967, in the first Block ii command Module, wearing early blue versions of the Block ii pressure suit.
6 cm-012 arrived at the kennedy Space center on August 26, labeled Apollo One by naa on its packaging. In October 1966, nasa announced the flight would carry a small television camera to broadcast live from the command Module. The camera would also be used to allow flight controllers to monitor the spacecraft's instrument panel in flight. 12 Television cameras were carried aboard all manned Apollo missions. 13 Insignia edit Grissom's crew received approval in June 1966 to design a mission patch with the name Apollo.
The design's center depicts a command/Service module flying over the southeastern United States with Florida (the launch point) prominent. The moon is seen in the distance, symbolic of the eventual program goal. A yellow border carries the mission and astronaut names with another border set with stars and stripes, trimmed in gold. The insignia was designed by the crew, with the artwork done by north American aviation employee allen Stevens. 14 15 Spacecraft preparation edit The Apollo 1 crew expressed their concerns about their spacecraft's problems by presenting this parody of their crew portrait to aspo manager Joseph Shea on August 19, 1966. The Apollo command/Service module was much bigger and far more complex than any previously implemented spacecraft design. In October 1963, joseph. Shea was named Apollo Spacecraft Program Office (aspo) manager, responsible for managing the design and construction of both the csm and the.

Slayton replaced him with Chaffee, 5 and nasa announced the crew selection on March 21, 1966. James Mcdivitt, david Scott and Russell Schweickart were named as the backup crew. 6 On September 29, walter Schirra, eisele, and Walter Cunningham were named as the prime crew for a second Block i csm flight, as-205. 7 nasa planned to follow this with an unmanned test flight of the lm (AS-206 then the third manned mission would be a dual flight designated as-278 (or as-207/208 in which as-207 would launch the first manned Block ii csm, which would then rendezvous and. 8 In March, nasa was studying the possibility of flying the first Apollo mission as a joint space rendezvous with the final add Project Gemini mission, gemini 12 in november 1966. 9 But by may, delays in making Apollo ready for flight just by itself, and the extra time needed to incorporate compatibility with the gemini, made that impractical. 10 This became moot when slippage in readiness of the as-204 spacecraft caused the last-quarter 1966 target date to be missed, and the mission was rescheduled for February 21, 1967. 11 Mission background edit Grissom declared his intent to keep his craft in orbit for a full 14 days. A newspaper article published on August 4, 1966, referred to the flight as "Apollo 1".
As-204 was to be the first manned test flight of the Apollo command/Service module (CSM) to earth orbit, launched on a saturn ib rocket. As-204 was to test launch self operations, ground tracking and control facilities and the performance of the Apollo-saturn launch assembly and would have lasted up to two weeks, depending on how the spacecraft performed. 3 The csm for this flight, number 012 built by north American aviation (naa was a block i version designed before the lunar orbit rendezvous landing strategy was chosen; therefore it lacked capability of docking with the lunar Module. This was incorporated into the Block ii csm design, along with lessons learned in Block. Block ii would be test-flown with the lm when the latter was ready, and would be used on the moon landing flights. 4 Director of Flight Crew Operations deke slayton selected the first Apollo crew in January 1966, with Grissom as Command Pilot, White as Senior Pilot, and rookie donn. But Eisele dislocated his shoulder twice aboard the kc135 weightlessness training aircraft, and had to undergo surgery on January.

Apollo 204 Accident review board to determine the reviews cause of the fire, and both houses of the. United States Congress conducted their own 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. The astronauts' rescue was prevented by the plug door hatch, which could not be opened against the higher internal pressure of the cabin. A failure to identify the test as hazardous (because the rocket was unfueled) led to the rescue being hampered by poor emergency preparedness. During the congressional investigation, then-Senator, walter Mondale publicly revealed a nasa internal document citing problems with prime Apollo contractor.
