S-33 Messenger

Role	Racer/Utility
National origin	United States
Manufacturer	Sikorsky
Number built	2

The Sikorsky S-33 Messenger was an American two-seat sesqiuplane designed and built by the Sikorsky Manufacturing Corporation in 1925.

The first of two examples built participated in the Sixth Pulitzer Trophy Race at Mitchel Field, Long Island, New York on October 12, 1925 and was piloted by Al Krapish, an employee of Sikorsky.^[1]

The first aircraft is reported to have been powered by a Wright Gale of 60 hp (45 kW) and the second by a Lawrance L-3 of 60 hp (45 kW). These were essentially the same engine type, post- and pre- acquisition of the Lawrance Aero Engine Company by the Wright Aeronautical Corporation, respectively. Some sources assert that the aircraft was powered by an Anzani engine, but this is most likely to be a mis-identification.^[2]
