Emergency evacuation tests of a crashed L-1649.

Four basic evacuation tests were performed on a crashed L-1649 in Phoenix, Arizona, to document problem areas, passenger reaction, emergency lighting, slope of flooring and other items affecting passenger egress.

Data were collected by tape recordings, motion picture film, and questionnaires. Observations were recorded
