Happy birthday, Paul Weitz, Skylab and Space Shuttle astronaut!
Paul Joseph Weitz, born July 25, 1932, is a veteran of the Skylab 2 mission and commander of the initial Space Shuttle Challenger flight. It was likely that he would have been chosen as Command Module Pilot for the Apollo 20 mission had it not been cancelled.
He's spent 793 hours in space. He performed an EVA during the Skylab mission lasting a little over an hour and a half.
