There was a month left before the launch of the ship. During training, a very strong fire occurred in the cockpit of the ship. The crew members who were training there were killed.
The cause of the fire was a short circuit in the wiring and the use of an explosive oxygen-nitrogen mixture. When the fire started, the cabin door was closed, and the astronauts had no opportunity to get out. Later, the commission found that they died within 14 seconds after the start of the fire.
Crew members:
Gus Grissom is the first astronaut to make two flights into space.
Ed White is the first US astronaut to go into outer space.
Roger Chaffee – had no flights into space, this flight was supposed to be the first.
