The Golden Age Of Aviation, the period in the history of aviation between the end of World War I 1918 and the beginning of World War II 1939. Charles Lindbergh's flight electrified the world and changed public opinion about air travel. On May 20, 1927, at 7:52 a.m., the Spirit of St. Louis accelerated down the runway off Long Island and lifted into the sky while a crowd of 500 watched. The plane barely cleared the telephone wires at the end of the strip. Length 5:00.
