Investigation Summary
The flight was a routine transport mission intended to bring key members of the Australian War Cabinet from Melbourne to Canberra for an urgent meeting regarding wartime resource allocation. The aircraft, a Lockheed Hudson Mk II, was nearly new and operating in ideal weather conditions. While some modern databases list the departure point as Moorabbin, that airport did not open until 1949; the flight actually originated from Essendon (then known as Melbourne Airport). Witnesses observed the aircraft abort its first landing attempt, climb, and then suddenly bank to the left and nose-dive into a hill approximately two miles from the aerodrome. The impact was followed by a fierce fire that hampered initial rescue efforts. The loss was catastrophic for the Australian government: the Minister for the Army, the Minister for Air, and the Minister for Information were all killed, effectively wiping out half of the War Cabinet during a critical period of World War II.
Final Conclusions
The RAAF Inspectorate of Air Accidents and a subsequent Service Court of Inquiry concluded that the immediate cause of the accident was an aerodynamic stall. The reports attributed the stall to an error of judgment by the pilot, Flight Lieutenant Robert Hitchcock. However, the RAAF Director of Training, George Jones, formally disputed this finding, citing Hitchcock's extensive experience. Historical theories have frequently suggested that James Fairbairn, the Minister for Air and an experienced pilot, may have been at the controls at the time of the stall; however, official coronial records stated bodies were burned beyond recognition, complicating definitive seat placement.

Known Controversies & Unanswered Questions
Identity of the Pilot at the Controls
Reference ↗There is a long-standing dispute over whether Flt Lt Hitchcock or Minister James Fairbairn was flying the plane. A 2020 account claimed Fairbairn was found in the pilot's seat, but this is contradicted by the 1940 coronial inquest stating bodies were unrecognizable.
