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.

Sailors aboard the USS Leviathan (formerly the Vaterland) in New York harbor, during World War 1, when she was serving as a troop ship. They are seen practicing emergency drills, including lowering lifeboats over the side and actually rowing them away. They also launch rubber rafts over the rails. U.S. Army soldiers from a lower deck, then descend to the rafts, using the lines from above. They are seen steping into the water-filled rafts and from there, into the lifeboats. Closeup of one soldier swimming in full uniform, with aid of floatation gear. He also relaxes in the water, suspended entirely by his life vest. View from above of a lifeboat crewed by sailors and filled with soldiers in uniform. They row away, pulling a raft, from which they help a few more soldiers into the lifeboat. Sailors row the filled lifeboats away from the ship, each towing a raft behind them. (WWI. WW1)
U.S. Army pilots of 3rd Attack Group stand on a field with Curtiss P-1 Hawk aircraft behind.
