Adriaan claims no-one could escape from Alcatraz. In truth, about 14 attempts at escape were made, with several of them really managing to get of the island. Theodore Cole and Ralph Roe escaped on December 16, 1937, but might have drowned in the ocean. John K. Giles managed to escape on July 31, 1945, but was apprehended on Angel Island the same day. Most notably was the escape of Frank Morris, John Anglin and Clarence Anglin on June 11, 1962, who might have survived their escape.
