Section states that cabin atmosphere is pure oxygen. This only happens in orbit after exiting earth's atmosphere and entering orbit. The cabin starts on the launch pad at a mix of 60% oxygen 40% nitrogen to reduce fire risk and is then gradually replaced with pure oxygen. Should the difference between in-earth-atmosphere and in-vacuum cabin atmosphere be explained? Niaaro (talk) 21:37, 8 January 2026 (UTC)Reply

I believe these documents have been moved to the NTRS archive. If someone has the time, please correct the references. OwlCritique (talk) 04:28, 23 March 2026 (UTC)Reply
