1. World War II- Part 38-(1940) United States getting closer to War. Latest planes for 1940. NOTE: Old video has no sound. First plane features a aileron wing. Ailerons- (French for little wing) are hinged flight control surfaces on the trailing edge of an aircraft's wings that control roll (banking) by moving in opposition—one goes up, the other goes down—to change the lift on each wing, enabling the aircraft to bank for turns. This movement is controlled by the pilot's stick or yoke, directing the aircraft to roll left or right around its longitudinal axis. Ailerons are not new having been around for about 30 + years by then. Also featuring the newly created Giant Bomber, the XB-24 With newer versions eventually becoming known as the B-24 Liberator Bomber. 18,482 B-24 Liberators—more than any other Allied aircraft type—were built during World War II. During World War II, the B-24 served in every combat theater. As the war came to an end, hundreds of brand new B-24s were accepted by the Air Corps, but sent immediately to be scrapped rather than placed in service. Did you notice how the aileron winged plane takes off very steeply after it has landed?
