What air craft ended production in 1992 and was derived from the same aircraft as the Boeing C-137 Stratoliner?
Boeing E-3 Sentry The Boeing E-3 Sentry, commonly known as AWACS, is an American airborne early warning and control (AEW&C) aircraft developed by Boeing as the prime contractor. Derived from the Boeing 707, it provides all-weather surveillance, command, control, and communications, and is used by the United States Air Force, NATO, Royal Air Force, French Air Force, and Royal Saudi Air Force. The E-3 is distinguished by the distinctive rotating radar dome above the fuselage. Production ended in 1992 after 68 aircraft had been built.
Boeing 314 Clipper The Boeing 314 Clipper was a long-range flying boat produced by the Boeing Airplane Company between 1938 and 1941. One of the largest aircraft of the time, it used the massive wing of Boeing’s earlier XB-15 bomber prototype to achieve the range necessary for flights across the Atlantic and Pacific Oceans. Twelve Clippers were built; nine were brought into service for Pan Am and later transferred to the U.S. military. The remaining three were sold to British Overseas Airways Corporation (BOAC) by Pan Am and delivered in early 1941.
