It wasn't just Apollo 11, it was Apollo 11-16. What blew me away about this was the fact that this was, in essence, DIY life-insurance because they couldn't get insurance. I never gave it much though; I just assumed that the U.S. government would have agreed "okay guys, if you get killed going to the moon, we'll make sure your families are taken care of". Guess not? From the Wikipedia page on Apollo Insurance Covers "The ability of astronauts to obtain much life insurance was limited, so they signed hundreds of postal covers before they left, on the presumption that they would become highly valuable in the event of their death." https://en.wikipedia.org/wiki/Apollo_insurance_covers
