Given the high risk nature of their jobs, life insurance would have been cost prohibitive. I am sort of surprised that there was nothing in NASA's budget, say $100K/head set aside, if the worst case scenario unfolded (as in the case of the Apollo 1 accident).
Neil almost bought it on the LEM simulator; he had to punch out maybe a couple of hundred feet (if that) off the ground.
All of those guys were maniacs. The mortality rate among test pilots was fairly high. Armstrong flew fighter jets in Korea, flew the Bell X Series planes, etc. Then was in the Gemini and Apollo programs. Amazing that he lived to a ripe old age. Chuck Yeager is still alive, pushing 90.
Neil was buried yesterday, the day of a blue moon. Seems appropriate.
