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 Armstrong Whitworth A.W.38 Whitley was a British medium bomber aircraft of the 1930s. It was one of three twin-engined, front line medium bomber types that were in service with the Royal Air Force (RAF) at the outbreak of the Second World War. Alongside the Vickers Wellington and the Handley Page Hampden, the Whitley was developed during the mid-1930s according to Air Ministry Specification B.3/34, which it was subsequently selected to meet. In 1937, the Whitley formally entered into RAF squadron service; it was the first of the three medium bombers to be introduced.
