A demonstration of the Aeronca GT-1 glide torpedo. Six Boeing B-17 Flying Fortress bombers, of the U.S. Army Air Forces, fly in formation. Next, splashes from their guided bombs are shown in water below. A slate appears with illustration and title, "Preset Glide Torpedo Model GT-1." A GT-1 is shown rotating while hung from a chain in a manufacturing area. Another Aeronca GB-1 is on the floor in the background. Four airmen push a GT-1 on a wheeled dolly. They roll it and position it underneath the wing of a B-17. Closeup of them jacking up the dolley to position the GT-1. View of the torpedo secured under the aircraft. Gun camera footage shows a GT-1 on a long glide towards the water, after release from above. View from water surface of the GT-1 approaching the water. At the last moment, its paravane (wing) separates and the torpedo contacts the water. The paravane falls aside into the water. The camera pans over to a makeshift target. The process is repeated with a second GT-1 but it is not seen close to the water. A third demonstration is successful and the wake of the torpedo is tracked from an overflying aircraft.
