Gemini 3: first test of the manned Gemini capsule; 3 orbits, a change in orbit and he smuggled a sandwich aboard...

Gemini 10 (related by Collins): 2 Agena rendez-vous, a record altitude at the time, an Agena kicking them to a higher orbit.
Not a single picture of the spacewalk exists (camera drifted outside).

Apollo 10 (related by Cernan): second flight to the Moon, first test of the LM in Lunar orbit; Young was in the CM; the crew still holds the absolute human speed record (just before hitting Earth's atmosphere).

Apollo 16 (related by Duke): last live from the Moon TV program I remember seing: absolutely beautiful images; One of the 3 most spectacular voyages of exploration (the J flights).

STS 1: long awaited , very nervous first test of a really huge vehicle!

STS 9: first time I see the Shuttle in orbit from home (well, I had to go to the port, actually, but I saw it).

He should have commanded the Hubble to orbit mission.
