Here’s a photograph from the August 25 1936 edition of the Toronto Daily Star of a man who was designing a plane that he hoped would set a speed record.
Harry Crosby went on to sustain serious back injuries when testing his CR-3 plane (which might have been this one). Undeterred, he designed the CR-4 plane while recovering, and finished in third place in the 1939 Greve Trophy race, part of the National Air Races. His plane was unofficially clocked at 386 mph in one test flight, which would have given him the record.
Crosby later flew as a test pilot for Northrop, and was killed in 1945 when testing the Northrop XP-79 flying wing fighter aircraft, which was later abandoned. His CR-4 plane was featured in the movie Tail Spin (1939). YouTube has two excerpts from this film:
