Gemini IX Thomas P. Stafford and Eugene A, Cernan stuck protective shroud and bad fogging on his visir no dock done?
OK!
I give you 100%.
The other instance was GT-9A, June 1966!
You got it right...that was some serious stuff.
And it was Gene Cernan involved in some serious trouble aloft.
Gene, of course, became the Lunar Module Pilot on Apollo 10, and the Commander of Apollo 17, and thus, the last man on the Moon.
The stuck shroud on the ADTA wasn't the serious trouble. That was an annoyance.
The real problem came on the EVA.
The plan was a bit too expansive and the effort required caused some very serious difficulty physically for Geno. Leverage problems, physical exertion to due inadequate hand holds, fogging of his visor due to inadequate cooling, and the physical effort which caused his heart rate to approach 200 BPM were all very serious difficulties.
There was a point where flight surgeons feared he might pass out. He actually had no visibility inside the suit when Tom Stafford was attempting to help him back inside the spacecraft....and there was thought that Geno might not be able to get back in, and that he might die in the process...which would necessitate re-entering the atmosphere with his body attached to the spacecraft by the umbillical, since it was deemed unacceptable to cut him loose, acxcording to Tom Stafford (although I often wondered how one might close the hatch with the umnbillical still attached to ther astronauts suit).
At any rate, they did manage to get him back in, and I'll never forget Stafford saying something to the effect of, "I don't think I'd like to try that again..."
That was the other actually critical problem that occurred among the three moon-walkers I spoke of. It rather speaks to the risks and difficulty inherent in manned space flight, and exploring unknown realms.
Thus, I declare, DONTEATUS got the answer, and is now entitled to ask the next question!
