The Sikorsky S-29-A was a twin-engine sesquiplane airliner, first flown in 1924. It was the first aircraft that aviation pioneer Igor Sikorsky designed and built after coming to the United States, hence the special "-A" suffix signifying "America". The aircraft made many successful long-range flights, most of which Sikorsky piloted himself. The S-29-A claims a number of "firsts" in aviation, including the first twin-engine aircraft capable of maintaining altitude on one engine, the first aircraft to broadcast a radio musical program in-flight, in 1925 and in 1926 the first aircraft to display a motion picture in flight. The S-29-A was also one of the first aircraft to make use of an airstair door, located on the starboard side of the fuselage.
