Apollo 1 Mission Capsule After Fire

Apollo 1 Capsule Mission After Fire

On January 27, 1967 the crew of Apollo/Saturn 204 (more commonly known as Apollo 1 mission) were training for the first crewed Apollo mission, an Earth orbiting mission scheduled to be launched on 21 February. The Command Module was mounted on the Saturn 1B on the launch pad just as in the actual launch, but the rocket was not fueled, no launch was planned.

This test was a simulation, going through an entire countdown sequence. On board were astronaut Virgil I. "Gus" Grissom, (the second American astronaut to fly into space) astronaut Edward H. White II, (the first American astronaut to "walk" in space) and astronaut Roger B. Chaffee, (a "rookie" astronaut on his first space mission).

At 1:00 PM the crew entered the capsule. From the beginning, there were problems. Several minor problems appeared, delaying the process quite a bit. Finally, a communications failure caused a hold to be placed on the count at 5:40 PM.

At 6:31 PM, a voice (later believed to be Roger Chaffee) exclaimed, “Fire, I smell fire.” Two seconds later, Ed White voice came over the circuit, “Fire in the cockpit.” The final voice transmission from crew was very garbled. “They’re fighting a bad fire—let’s get out. Open ‘er up” or, “We’ve got a bad fire—let’s get out. We’re burning up” or, “I’m reporting a bad fire. I’m getting out.”

The fire spread quickly through the cabin, the oxygen rich atmosphere which had seeped into the materials of the cabin had caused the fire to spread rapidly. The hatch was held closed by several clamps which required extensive ratcheting to release. Under the best of circumstances, it could take at least 90 seconds to open. Since it opened inward, pressure had to be vented before the hatch could be forced open. It was nearly 5 minutes after the start of the fire before rescuers could get into the cabin.

The crew most likely perished within the first 30 seconds from smoke inhalation or burns. Resuscitation efforts were futile.

A hold was placed on the entire Apollo program while an investigation was made into the accident. Although a reason the fire started could not be determined, the final report of the investigation board blamed the fire on arcing. It was made worse by the large quantity of flammable materials in the cabin and the oxygen enriched atmosphere.

For future missions, most flammable materials were replaced with self-extinguishing materials. Pure oxygen was replaced by a nitrogen-oxygen mixture at launch. Finally, the hatch was redesigned to open outward and to be able to be removed quickly.

The Apollo/Saturn 204 mission 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).
