A U.S. Army Air Force Curtiss P-40 pursuit plane is set up with engine running and prop turning, during test of its machine guns at Wright Field, Dayton, Ohio. Cameramen stand on a stand and record the action from behind the right horizontal stabilizer. Its 50 caliber machine guns are seen firing through through the spinning propeller, with which they are synchronized while its 30 caliber guns fire from the wings. The gunfire is directed at a target set within an earthen revetment, on a remote part of the airfield. Bullets are seen tearing through the target and churning the earth behind. Glimpse of the control panel inside the cockpit, where engine instruments read normal for engine-running condition. Flight instruments are inactive and altimeter reads 800 feet ( Wright field elevation). Gloved hand of person test firing the guns is seen on the control stick. Quartering front view of the aircraft during firing including closeup of the twin 50 caliber machine guns firing from atop the engine nacelle. More views of guns firing. In the last scene, photographers are shown hunkered down beneath the aircraft right wing with their cameras. (World War II period).
