Frank Morris, and brothers John and Clarence Anglin accomplished such great feats to escape Alcatraz, it’s hard to believe they went through all they did only to drown in the San Francisco Bay. Some believe that’s exactly what happened, because the idea of floating through icy waters on an inflatable raft and not dying seems a bit fantastical. However, researchers found that if the men did everything right, they could have made it to shore.

The only way you could manage all that noisy digging without being caught is to cover it up. Frank Morris practiced his accordion in the evenings, which concealed the sounds of impending escape.
