Abstract
An escape system for descending a person from a window is disclosed. The escape system may be mounted above a window through which a person may egress and descend to the ground. The escape system includes a fenestration unit having a frame and a human support embedded into the frame in a stowed position. The human support carries a person during descent. A cable is wound about a shaft supported by the frame. The cable is connected to the human support. The escape system further includes a speed limiting device connected to the shaft that controls the speed of descent.
