"1962 -
• Fire in a simulated Air Force space cabin Nation: USA.
Program: Apollo. Spacecraft: Apollo CSM.
• Fire broke out in a simulated space cabin at the Air
Force School of Aerospace Medicine, Brooks Air Force Base, Tex., on the
13th day of a 14-day experiment to determine the effects of breathing
pure oxygen in a long-duration space flight. One of the two Air Force
officers was seriously injured. The cause of the fire was not
immediately determined. The experiment was part of a NASA program to
validate the use of a 5 psia pure oxygen atmosphere for the Gemini and
Apollo spacecraft."


Yet the continued to use a pure oxygen atmosphere until Apollo1 five
years later?
