On July 21, 1969 at 02:56 UTC, Neil Armstrong forever stamped his name in the history books by putting his foot on the Moon. Armstrong getting to do this almost never happened due to the fact that he turned his application in to NASA about a week after the June 1, 1962 deadline, making him ineligible for that historic second round of astronaut hirings.
The famous bank robber John Dillinger was once a professional baseball player. In fact, an umpire in the professional league Dillinger played in helped him plan and was the getaway driver in Dillinger's first robbery. Later, in prison, Dillinger played shortstop for the Indiana State Reformatory ball club. It has even been speculated that he was transferred to the Indiana State Prison in Michigan City as they needed a good shortstop, and Dillinger by all accounts was a great player.
