Gee Bee Q.E.D.

The Gee Bee Q.E.D. Quod Erat Demonstrandum aka Gee Bee R-6H aka the Conquistidor del Cielo (Conqueror of Heaven) was the last in a series of racing and touring aircraft from the Granville Brothers. Unlike the other famous Gee Bee aircraft the Q.E. D had the distinction of never finishing a race it was entered in.

In 1935 Leonard was first to fly the new Gee Bee Q.E.D. in the Bendix Race. Leonard was forced down with engine trouble at Wichita, Kansas.1
