The Incredible Alcatraz Prison Break !

The Plan 

The FBI were aided by Allan West, who didn't make it out of his cell and began providing them the details. The men concealed their absence while working outside their cells—and after the escape itself—by sculpting dummy heads from a hand-made paper mixture of soap, toothpaste, concrete dust, and toilet paper, and giving them a realistic appearance with paint from the maintenance shop and hair from the barbershop floor. With towels and clothing piled under the blankets in their bunks and the dummy heads positioned on the pillows, they appeared to be sleeping. They also assembled a six-by-fourteen-foot rubber raft, the seams carefully stitched by hand and sealed with heat from nearby steam pipes. Paddles were improvised from scrap wood and screws.

The Escape

 On the night of June 11, 1962, after all the preparations were made, the men began planning. West found that the cement used to reinforce the collapsing concrete around the vent had hardened, narrowed the openings, and fixed the grid. By the time he managed to get rid of the grid and reopen the hole, others had left without him. He returned to his cell and fell asleep. An unprotected supply corridor behind the refugee cell. From the maintenance corridor, Morris and Anglin climbed the ventilation tower to the roof. The guards heard a loud crash when erupting from the shaft, but heard nothing more and the cause of the noise was not investigated. They carried gear, slid down the kitchen flue, descended 50 feet (15 m) to the ground, and then climbed two 12-foot (3.7 m) barbed wire fences. Near the power plant on the northeast coast (the searchlight of the prison and the blind spot of the turret), they inflated the raft with an accordion stolen from another prisoner and turned it into a bellow. After 10 pm, investigators estimated that they boarded the raft, inflated it, and headed for their destination.
