Executing The Plan

From the service corridor, Morris and the Anglins climbed the ventilation shaft to the roof. Guards heard a loud crash as they broke out of the shaft, but since nothing further was heard, the source of the noise was not investigated. Hauling their gear with them, they descended 50 feet (15 m) to the ground by sliding down a kitchen vent pipe, then climbed two 12-foot (3.7 m) barbed-wire perimeter fences. At the northeast shoreline, near the power plant—a blind spot in the prison's network of searchlights and gun towers they inflated their raft with the concertina. At some time after 10 p.m., investigators estimated, they boarded the raft, launched it and departed toward their objective, Angel Island, two miles to the north.
