The Bakers Creek air crash was an aviation disaster that occurred on 14 June 1943, when a United States Army Air Forces (USAAF) Boeing B-17 Flying Fortress aircraft crashed at Bakers Creek, Queensland, Australia. The aircraft took off from Mackay and crashed approximately 8 km (5.0 mi; 4.3 nmi) south of the airfield. Forty military service personnel on board were killed; one person survived the crash. The crash is Australia's deadliest aviation disaster by death toll and was the deadliest accident involving a transport aircraft in the south-western Pacific during World War II.
