Warplane

The A-10 is the Air Force's unlikely success story, an airplane designed to support the Army, and one that ground troops came to venerate. Originally conceived with the express purpose of destroying Soviet tanks, the Air Force only developed it to keep funding away from the Army's response to the mission, the AH-56 Cheyenne helicopter. Inspired by the biography of a tank-busting German pilot in World War II, the engineering and design of the A-10 fell to Pierre Sprey, a precocious civilian who'd enrolled at Yale when he was just 15-years-old, and now, barely 30, was exiled to a Pentagon backwater with little, if any, supervision. The end result was one of the finest military aircraft ever built, a plane essentially constructed around a 19.5-foot, 4,000-pound cannon that fired 30mm depleted uranium bullets at a blistering rate.
