A review of research and development in guided missiles by the United States Air Force from 1919 to 1948. A GB-7 missile crashes in a scrubby wooded area. A GB-7 missile is assembled in a work laboratory. Men remove the protective cover from the nose section of the radar unit. A technician starts operating the radar unit in the nose section of the missile. The radar unit in operation. A radio control unit is mounted on the tail assembly of the bomb. Demonstration of the small stick control radio unit and control sections of the Azon bomb. A B -24 Liberator in flight drops a single Azon bomb. The bomb hits a bridge across a river. Multi drop of Azon bombs shows many smoke trails left by flares attached to the tail section of the bomb. The bombs drop on parallel course with a road leading through a wooden area. Razon bomb suspended from a chain hoist. Inserting a flare unit into the tail section of the Razon bomb. Two bombs are dropped at the same time. A technician works on the heat seeker section of a GB-6 free falling missile. A British Tall Boy bomb. The Tall Boy is the VB-13 bomb.
Wright brothers' first flight together near Dayton Ohio in 1910. Wilber is in the pilot's seat with Orville as passenger to his right.(Until this flight, the Wrights had never flown together so that if one of them was killed, the other could continue their work.) Next, a view of Alberto Santos-Dumont, and the first European flight made by him on 13 September 1909. Following segment shows crowds gathered at Washington DC Polo field as truck arrives carrying mail to be loaded on the first U.S. Air mail flight, May 15, 1918. Army pilot, Lieutenant Webb, in his JN-4H airplane, on Southbound flight from New York, takes off from Philadelphia, where he stopped to pick up more mail. He flies over the Washington Polo Field upon arrival. We see his airplane being unloaded as he jumps down from cockpit and crowds watch. Views of first transatlantic flight begins with takeoff of three out of four existing United States Navy Curtiss flying boat aircraft from Newfoundland, on May 16, 1919. Curtiss flying boats NC-1, NC-3, NC-4 are seen at takeoff from Newfoundland on first leg of the transatlantic journey. Flying Boat NC-4 is also seen at one of its foreign ports, though which is unclear (Azores, Lisbon, or England).
Location is the Ellipse, south of the White House, in Washington, DC. The occasion is the dedication of a temporary Zero milestone in ceremonies at the start of the U.S. Army Motor Transport Corps'so-called "Truck Train," a convoy of military vehicles that is to travel the "Lincoln Highway" across the United States, to San Francisco, California. The ceremony begins with a flag raising, where all stand and uniformed Army officers salute. Congressman Julius Kahn, of California, salutes with his hat over his heart. The temporary marker is covered with white cloth and two wreaths, which officials remove and Secretary of War Newton D. Baker, begins his speech accepting the temporary marker. (A permanent marker needed an act of Congress for approval. So a temporary one was approved to allow the launch of the Army cross-country convoy.) The Washington Monument is visible in the background, as Mr. Baker delivers his remarks.
