Were all the Apollo flights made in a one-gas (pure oxygen)
environment? It seems that the thin skin of the LM made it necessary
to limit the cabin pressure to 3.5 psi and required a one-gas system.
Is this correct?
Yes.
To detail a bit more. All took off with a mixed gas atmosphere (N2 and O2)
at I believe 1 atmosphere pressure.
The N2 was bled off until the they reached the partial pressure of the O2
was left.
