Brockway Air
Northern Airways' initial fleet consisted of the deHavilland Canada DHC-6 Twin Otter STOL (short take off and landing) capable commuter turboprop airliner.Powered by Rolls-Royce Dart engines, the Grumman I-C was used by Air North on routes requiring greater speed and passenger capacity than was possible with the airline's Shorts 330s.Clinton Aero had been formed to operate to several small cities in northern New York state, replacing service previously provided by Air North.These included US Air and Empire Airlines, both with route networks heavily focused on the New York state and Northeast markets that Brockway served.Roach, John; Eastwood, Tony (1990), Turbo Prop Airliner Production List, West Drayton, Middlesex UK: The Aviation Hobby Shop, ISBNÂ 0-907178-32-4
