The Apollo 1 tragedy
27 January 1967
Edward White, Command Pilot
Virgil "Gus" Grissom, Commander
Roger Chaffee, Pilot
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.

Remembering the Apollo 1 Crew
On
Jan. 27, 1967, veteran astronaut Gus Grissom, first American
spacewalker Ed White and rookie Roger Chaffee (left-to-right) were
preparing for what was to be the first manned Apollo flight. The
astronauts were sitting atop the launch pad for a pre-launch test when a
fire broke out in their Apollo capsule. The investigation into the
fatal accident led to major design and engineering changes, making the
Apollo spacecraft safer for the coming journeys to the moon.

Cape Kennedy, Fla.,
Jan. 27 -- The three-man crew of astronauts for the Apollo 1 mission
were killed tonight in a flash fire aboard the huge spacecraft designed
to take man to the moon.
Those killed in the blaze on a launching pad were:
VIRGIL I. GRISSOM, 40 years old, Air Force lieutenant colonel, one of the seven original Mercury astronauts.
EDWARD H. WHITE 2d, 36, a lieutenant colonel in the Air Force, the first American to "walk" in space.
ROGER B. CHAFFEE, 31, a Navy lieutenant commander, who had been awaiting his first space flight.
The astronauts were the first American spacemen to be killed on the
job and ironically, died while on the ground. The bodies were removed
hours later and a space agency spokesman said death was "instantaneous."
Three other astronauts died in airplane crashes, in the line of duty,
but today's tragedy involved the first "on premises" deaths in the
American space program- the first time anyone was killed while in space
hardware.
Simulation Under Way
The fire broke out at 6:31 P. M. while the three men were taking part
in a full-scale simulation of the scheduled Feb. 21 launching that was
to take them into the heavens for 14 days of orbiting the earth.
They were trapped behind closed hatches, according to the National Aeronautics and Space Administration.
[Officials said an electrical spark must have ignited the pure oxygen inside the cabin, United Press International reported.]
Paul Haney, spokesman for America's astronauts, said he understood
there had been a fire in the cockpit. He said monitors had received no
word from the astronauts during the fire.
Mr. Haney said 26 members of the launching pad crew were treated for
smoke inhalation. He said 24 were released and two were hospitalized in
good condition.
Space agency officials were alerted by someone on the ground that the
fire had broken out, Mr. Haney reported. He said emergency crews tried
to reach the astronauts but were blocked by the dense smoke that rolled
out of the cockpit.
Officials at Cape Kennedy said that the three astronauts were seated
abreast in the rocket in the exercise, just as they would be in actual
flight, with Colonel Grissom occupying the command pilot's seat on the
left, Colonel White in the middle, and Commander Chaffee on the right.
In Washington President Johnson mourned the death of the astronauts.
He said the three men had given their lives in the nation's service.
Representative Joseph E. Karth, Democrat of Minnesota, said a dinner
meeting of space program executives was underway in Washington when the
announcement was made that there had been "a flash fire resulting from
the use of pure oxygen..." He said no further explanation had been given
at the dinner.
The fire was reported during a "plugs out" test of the booster and
Apollo 1 craft. Mr. Haney said the test meant that the booster and
spacecraft had been operating on their own poser systems and not power
from the ground.
NASA officials later said the Apollo's escape system could not have
been used. The system required an astronaut to trigger a rocket attached
to the top of the Apollo. The rocket would jerk the spacecraft away
from its booster.
A spokesman said a gantry and been wrapped around the entire rocket
during today's test, enclosing the escape rocket. He said the only way
the astronauts could have escaped would have been to open the hatches
and scramble out.
Mr. Haney said the rehearsal had reached the minus 10-minute mark,
meaning it was 10 minutes away from a simulated liftoff. The hatches
were sealed.
A NASA official said minor difficulties had cropped up during the
countdown with two systems, a communications system and the
environmental control system.
Cause of Fire Unknown
Officials said they did not know whether the fire stemmed from the
two troublesome systems. All data were held pending an investigation.
Space officials said the three victims possibly had no knowledge
there was a serious problem aboard. The spacecraft and rocket were not
fueled and explosive devices aboard the spacecraft had been inactivated
and could not have caused the disaster, they said.
The Air Force and NASA jointly impounded all data. The space agency
said reporters would not be permitted to the scene until tomorrow
morning at the earliest and any pictures of the incident that might
reveal details were also being withheld.
The backup astronauts for the scheduled 14-day flight-postponed indefinitely- now become the prime pilots for Apollo 1.
