Norway

The aircraft was performing a flight from RAF Down Ampney to Oslo with an intermediate stop in Copenhagen. While approaching the Oslo-Fornebu Airport from the north, both engines lost power due to icing conditions. The captain decided to go around when the aircraft hit the slope of a hill located in Voksenkollen, north of the capital city. On scene, rescuers were able to evacuate two wounded passengers while 15 other occupants were killed. Few hours later, both survivors died from their injuries.

During the takeoff roll, prior to liftoff, the landing gears were prematurely retracted, causing the aircraft to fall on runway. The Dakota slid for several yards and then veered off runway to the right before coming to rest. While there were no casualties, the aircraft was damaged beyond repair.

The crew was performing a flight from RAF Great Dunmow to Oslo-Gardermoen Airport, taking part to the operation christened 'Doomsday' of releasing Norway from the German occupation. The descent was started in poor weather conditions with low clouds, fog and rain showers. On approach, while too low, the aircraft hit the slope of a mountain and crashed, killing all 24 occupants.
