Flew Panthers from a carrier in Korean War, X-15, Gemini 8, Apollo 11 and a number of other aircraft, many of them experimental. Tested F-100, F-104, F-105, F-106, KC-135 and B-47, among other aircraft. First human to set foot on the moon, a member of a Scottish clan Armstrong (that's right, he even had a piece of Armstrong tartan with him on the moon). Investigated Apollo 13 and Challenger explosion. USN Lieutenant, Junior Grade and all round badass. It's hard to believe that all this was done by one man, in one life, but there you have it.
So, rest in peace, Armstrong, you earned it.
