Originally delivered to Pan American in 1940 as NC19903. After several sales, including service with the Haiti Air Force (1953) and storage, it was moved to Davis-Monthan for preservation in 1973, the last intact survivor of 10 built. Seen here in the markings of its last operator, it was later restored to its original Pan Am livery in 1994 and flew again in 2001. Following a ditching incident in Elliott Bay, WA in 2002, the aircraft was recovered, restored to flying condition, and finally flown to Washington-Dulles, VA in 2003 for permanent preservation with the National Air and Space Museum
