Henry Harley "Hap" Arnold was an American general officer holding the grades of General of the Army and General of the Air Force. Arnold was an aviation pioneer, Chief of the Air Corps, Commanding General of the U.S. Army Air Forces during World War II, the only Air Force general to hold five-star rank, and the only person to hold a five-star rank in two different U.S. military services. Arnold was also the founder of Project RAND, which evolved into one of the world's largest non-profit global policy think tanks, the RAND Corporation, and one of the founders of Pan American World Airways. Instructed in flying by the Wright Brothers, Arnold was one of the first military pilots worldwide, and one of the first three rated pilots in the history of the United States Air Force. He overcame a fear of flying that resulted from his experiences with early flight, supervised the expansion of the Air Service during World War I, and became a prot�g� of Gen. Billy Mitchell. [More at Wikipedia]
