According to Gustave and the single eyewitness to the event, the monoplane's longest flight was 60 meters (200 feet) above ground for 2.5 kilometers (1.5 miles). However, these claims are contested. Gustave failed to keep a log book and planned for the bulk of his flights to occur at night, or "early dawn", thus limiting witnesses.

An article in the August 18, 1901 issue of The Bridgeport Herald states that the author states he witnessed a night test of the plane, at first unpiloted but loaded with sand bags, and later with Whitehead at the controls.

Number 21 was a monoplane powered by a 20 hp engine, fueled by acetylene. It achieved takeoff speed by using the engine to power the wheels, as in an automobile; upon takeoff, power was switched to the propeller.
