I love the part where someone says Neil Armstrong had to eject from the lunar trainer earlier in the day and no-one believed it. He was busy doing paperwork. When quized, he admited "yep", or some such thing, then went back to work. Seconds from death, but just "another day at the office"
I guess the guys were topshot test pilots usually before getting into NASA.
Excellent documentary, and well worth a watch especially now Neil has just left us.
