Various types of aircraft move down the runway and take off. Three planes in formation are seen from the air. Viewed from the cockpit, a pilot is at the controls. A hydroplane gets ready to land in a British port. Seen from the air, bombs fall on the battlefield. An enemy plane is pursued by fire from an anti-aircraft battery, while another spirals down and crashes on the ground.
