Vertical Flight Society Award Recipients


Grover E. Bell Award

The Grover E. Bell Award is given for an outstanding research and experimentation contribution to the field of vertical flight development brought to fruition during the preceding 18 months. The Grover E. Bell Award was created by Larry Bell, founder of Bell Aircraft (now Bell Textron) in 1957, in honor of his pioneering older brother, Grover E. Bell, who was killed in an aircraft crash in 1913. Eligible contributions include sub-systems as well as systems. The award consists of a 3-inch gold medal bearing the profiles of Lawrence and Grover Bell, and a certificate.
