DeKellis-Olson Air Truck: Dumpy Tri.

1957 DeKellis-Olson Air Truck: Dumpy Tri.

This is Mr. Thomas E.DeKellis’ idea of the perfect crop duster aeroplane. Not satisfied with the modified aircraft then available, he thought an triplane design would do better a better job. With that formula he intended to improve both maneuverability and carrying capacity. As a plus, those qualities were perfect not only for a duster, but also for a heavy duty light cargo aircraft. He was ambitious…
All in all, only this prototype was built with BT-13 surplus pieces by mechanic Alan Olson in 1957. Flown and soon forgotten.

It sure looked like an old abused mule.
