Wheeler Flying Service was certificated by the FAA as an air carrier and a repair station.
In 1975, Wheeler Airlines briefly operated a de Havilland Canada DHC-6 Twin Otter.
The routes expanded to Wilmington, Delaware, Washington, DC and Tri Cities, Tennessee.
[6][7] Many of the pilots were trained at Wheeler Flying Service under the Federal CEDA Program.
When they reached 1,200 hours flight time they were assigned to fly courier routes in piston airplanes.
All of the pilots gained valuable turbine time while employed at Wheeler Airlines and the vast majority of Wheeler Airline co-pilots black and white were or still are employed as pilots at major air carriers.
