The escape went like this...
On June 12, 1962, 3 men tested their luck. John Anglin, Clarence Anglin, and Frank Morris built dummy heads made of plaster, flesh-tone paint, and real human hair that successfully fooled the night guards. The prison went into lock down, and the search began. Intensive hours spent by the FBI trying to uncover where they were led to nothing but more confusion. A few pieces of evidence turned up, such as a packet of letters related to the men, pieces of wood and bits of rubber found in the water, and a homemade life- vest, but nothing significant. FBI did uncover a fourth person that was supposed to join them in the escape but didn't make it out of his cell in time. He provided them with information as to how they escaped.
- They began making plans for the escape 7 months prior- they started with widening the ventilation duct in Morris's cell wall using sharpened spoons and discarded saw blades and then hid the holes with painted cardboard
- Behind the cells was an unguarded utility corridor. They made their way down this corridor and climbed to the roof of their cell block inside the building, where they set up a secret workshop- each took turns working while the others kept a look out for guards
- they were able to steal 50 raincoats and from that they made makeshift life preservers and a 6x14 foot rubber raft
- finally, they had to look for a way out of the building , the ceiling was 30ft high but they concluded that they could climb up the network of pipes to pry open the ventilator at the top
