Lodges covered with snow on a snowy mountain pass near Cumbres, Colorado. A narrow gauge train of the Rio Grande San Juan Extension (later the Cumbres and Tultec Scenic Railroad) plows its way through the snow of a Rocky Mountain pass near Cumbres. The locomotive engine of the train is equipped with a rotary snowplow that clears away the deep snow from the tracks. The train approaches two men waving.

An F6F Hellcat ditches in the sea. It floats long enough to allow pilot to abandon it before sinking. Next an A-4 Skyhawk ditches. Narrator remarks about the short time for escape from such aircraft on the surface of the water. Views of tests conducted by the U.S. Navy to test the sink rates of jet aircraft from various heights and attitudes. A dummy is placed in the cockpit of a derelict F9F Panther, which is lifted by a crane and is dropped into water from a low height. It is seen floating. (Narrator states that even with no structural damage, it sinks in less than a minute.) Next an FJ-2 Fury is dropped from about 55 feet. Due to structural damage, narrator states such an aircraft may sink in a few seconds, and generally between zero to 55 seconds. View of crane operator and then of an airplane sinking rapidly. Scene shifts to James F. Roth of U.S. Navy Attack Squadron 42,(VA-42) the "Green Pawns," in the closed cockpit of a Navy jet airplane. Next, an F-4 phantom jet is seen being catapulted from an aircraft carrier. Animation shows that the airplane falling into the sea right after takeoff will sink ballistically and can descend as deep as 100 feet in 10 seconds.
Animation shows method of escape from a jet when it submerges in water. It shows how the pilot has to come out from the cockpit in case of emergency. Pilot tests the method of escape from the jet in case of emergency. He takes the model of cockpit in the water reservoir made for the purpose. Then he ejects himself from the canopy, leaves the cockpit and ascends to the surface. Information given to the pilot: disconnect yourself, leave cockpit, ascend to the surface.
