What's that got to do with the fact that it was known well before the untimely demise of the Apollo 1 crew that combustion occurs more rapidly in a 100% oxygen environment, even without the Russians?
I’m trying remember how the book described the reason for my claim. Yes, I know we knew about the danger but the author described something that made the sharing of the particulars beneficial to crew that died in ‘67.
Do you recall seeing the famous class pictures of cosmonauts? Ones that later showed classmates airbrushed out? One was the young cosmonaut who perished in the O2 chamber, the other, if I recall was a alcholic who died in disgrace. If you have the time read the book of above, it was well documented and sourced..
