The Soviets had a cosmonaut trainee burn in an O2 environment, pre-Apollo. Maybe the first person to die in a modern space program.

He tossed an alcohol wipe towards a bin, it missed, and landed on an active hot plate. Probably should mention that he was removed sensor adhesive from his chest with the wipe.

Wow...I didn’t know about that.

I read somewhere that the O2 environment allowed them to have a lower air pressure in the cabin, something like 5 to 8 psi, which is a weight saving for the duration of the flight.
