Air Vice Marshal Donald Clifford Tyndall Bennett, was an Australian aviation pioneer and bomber pilot who rose to be the youngest air vice marshal in the Royal Air Force. He led the "Pathfinder Force" from 1942 to the end of the Second World War in 1945. He has been described as "one of the most brilliant technical airmen of his generation: an outstanding pilot, a superb navigator who was also capable of stripping a wireless set or overhauling an engine".

The Pathfinders were target-marking squadrons in RAF Bomber Command during World War II. They located and marked targets with flares, at which a main bomber force could aim, increasing the accuracy of their bombing. The Pathfinders were normally the first to receive new blind-bombing aids such as Gee, Oboe and the H2S radar.
