De Havilland Canada DHC-5 Buffalo
The de Havilland Canada DHC-5 Buffalo is a short takeoff and landing (STOL) utility transport turboprop aircraft developed from the earlier piston-powered DHC-4 Caribou. The aircraft has extraordinary STOL performance and is able to take off in distances much shorter than even most light aircraft can manage.
