It was on this date in 1962 that the only succesful escape from Alcatraz ever took place. By successful, of course, I mean that they actually got out of the prison. It is believed that they died while in the bay, though a few years ago MythBusters recreated the escape, and were able to do so. Each and every year, in honor of the escape, there is an Escape From Alcatraz triathlon in San Fran that includes a swim in the San Francisco Bay (which is currently a brisk 56 degrees.)
