Mmm, a list of greats there, but missing one of my favorites; Story Musgrave.
Too young to have gotten in on the start of the space age, but helped to establish the Skylab set of missions, and was deeply involved in the Shuttle program.
Brilliant idea of using a come-along to get Hubble's doors closed after his repair mission.
Plus the only dude to stand up in the cockpit during a Shuttle deorbit to videotape the plasma stream wash over the orbiter during reentry.
He's "old school", but open to new schools of thought.
Quite a character, sometimes a bit strange, but deserving of a spot in the pantheon of human spaceflight.
