The Apollo 1 tragedy

One of the worst tragedies in the history of spaceflight occurred on January 27,
1967 when the crew of Gus Grissom, Ed White, and Roger Chaffee were killed in
a fire in the Apollo Command Module during a preflight test at Cape Canaveral.
They were training for the first crewed Apollo flight, an Earth orbiting mission
scheduled to be launched on 21 February. They were taking part in a "plugs-out"
test, in which the Command Module was mounted on the Saturn 1B on the launch pad
just as it would be for the actual launch, but the Saturn 1B was not fueled.
The plan was to go through an entire countdown sequence.
At 1 p.m. on Friday, 27 January 1967 the astronauts entered the capsule on Pad 34
to begin the test. A number of minor problems cropped up which delayed the test
considerably and finally a failure in communications forced a hold in the count
at 5:40 p.m. At 6:31 one of the astronauts (probably Chaffee) reported,
"Fire, I smell fire." Two seconds later White was heard to say, "Fire in the
cockpit." The fire spread throughout the cabin in a matter of seconds. The last
crew communication ended 17 seconds after the start of the fire, followed by loss
of all telemetry. The Apollo hatch could only open inward and was held closed by
a number of latches which had to be operated by ratchets. It was also held closed
by the interior pressure, which was higher than outside atmospheric pressure and
required venting of the command module before the hatch could be opened. It took
at least 90 seconds to get the hatch open under ideal conditions. Because the
cabin had been filled with a pure oxygen atmosphere at normal pressure for the
test and there had been many hours for the oxygen to permeate all the material
in the cabin, the fire spread rapidly and the astronauts had no chance to get
the hatch open. Nearby technicians tried to get to the hatch but were repeatedly
driven back by the heat and smoke. By the time they succeeded in getting the
hatch open roughly 5 minutes after the fire started the astronauts had already
perished, probably within the first 30 seconds, due to smoke inhalation and burns.
The Apollo program was put on hold while an exhaustive investigation was made of
the accident. It was concluded that the most likely cause was a spark from a
short circuit in a bundle of wires that ran to the left and just in front of
Grissom's seat. The large amount of flammable material in the cabin in the oxygen
environment allowed the fire to start and spread quickly. A number of changes
were instigated in the program over the next year and a half, including
designing a new hatch which opened outward and could be operated quickly,
removing much of the flammable material and replacing it with self-extinguishing
components, using a nitrogen-oxygen mixture at launch, and recording all changes
and overseeing all modifications to the spacecraft design more rigorously.
The mission, originally designated Apollo 204 but commonly referred to as Apollo 1,
was officially assigned the name "Apollo 1" in honor of Grissom, White, and Chaffee.
The first Saturn V launch (uncrewed) in November 1967 was designated Apollo 4
(no missions were ever designated Apollo 2 or 3). The Apollo 1 Command Module
capsule 012 was impounded and studied after the accident and was then locked away
in a storage facility at NASA Langley Research Center. The changes made to the
Apollo Command Module as a result of the tragedy resulted in a highly reliable
craft which, with the exception of Apollo 13, helped make the complex and
dangerous trip to the Moon almost commonplace. The eventual success of the
Apollo program is a tribute to Gus Grissom, Ed White, and Roger Chaffee, three
fine astronauts whose tragic loss was not in vain.
