You'll believe two men can fly
With all the Olympic hoo-hah, it's instructive to watch Bob Beamon in the 1968 games in Mexico City, where he set a world and Olympic record for the long jump (and arguably eclipsed the Black Power salutes of two days earlier as the most memorable event of the games). The jump was nearly two feet longer than the previous world record, and it was widely predicted that it would stand until the end of the century.
Well, yes and no. Beamon's jump is still the Olympic record, but at the world athletic championships in 1991, Mike Powell jumped 5 cm further to set a new world record, which will soon have lasted as long as Beamon's did. Beamon's jump remains the second longest wind-legal jump in history.
