The Los Angeles Air Terminal provided the backdrop for the DC-1 on a visit in 1933, the year of the first flight of the historic airliner. Although only one DC-1 was built, TWA and other airlines ordered more than 130 DC-2s, a slightly modified version of the DC-1. The world-famous DC-3, which flew for the the first time in 1935, was simply the logical evolutionary development of the DC-1 and DC-2. Douglas Aircraft built more than 10,000 DC-3s, most of them as military transports designated the C-47.
