It is a little known fact that during the Apollo 11 mission, astronauts Armstrong, Collins and Aldrin had yet to decide who was going down to step, leap, walk, bounce and frolic on the surface of the Moon, and who was going to stay behind, orbiting in the command module.

After flipping a coin in the air and waiting for more than two hours without a definitive result due to the lack of gravity, Armstrong and Aldrin managed to convince Collins that it was best to go by alphabetical order, and thus history was made.
