Shortly after takeoff from Cunderdin Airport, while in initial climb, the aircraft reached the altitude of 30 feet when it drop back to the ground. It hit the ground 3 times and skidded through a fence about 800 feet from the end of the strip and exploded. Five crew members were killed while six others were injured. The aircraft was destroyed. The cause of the crash was unknown although one private theory was that the squadron had an absolute minimum of training flights.

The four engine aircraft crashed when attempting to land at Fenton Airfield, in the Northern Territory, following a bombing raid on Japanese shipping targets in Timor. The Liberator was out of fuel and losing height rapidly. It was just before midnight and conditions were very hazy and the pilot, Flight Lieutenant Arthur Cambridge, could not see the runway flare path. On his first approach to land, he was too far to the left of the runway. He was advised of this by radio contact with ground control. On his second attempt to land, three of the four fuel pressure gauges dropped to zero and the Liberator swung violently to port. Cambridge ordered the crew to crash positions and with his undercarriage still retracted the Liberator crashed through some trees 3 kilometers from Fenton Airfield and struck the ground in a more or less level attitude. A fire broke out below the flight deck, possibly due to damage to the auxiliary power unit. Two crew members were killed while nine other occupants were rescued.

During the day, technical anomalies were noted on the engines and the captain decided to perform a test flight. The twin engine aircraft left Richmond Airfield at 1620LT. Ten minutes into the flight, the captain informed ground about technical problems and elected to return to the airport. On final approach, while at a height of 200-300 feet, the left engine failed. The aircraft banked left, hit power cables and crashed in a huge explosion some 400 yards short of runway threshold. All eight occupants were killed.

After take off from Rose Bay in Sydney, the crew encountered technical problems with the flaps that should be raised manually because the electric flap motor failed. Twenty minutes into the flight, the flight oil pressure on starboard inner engine fell below normal levels. The captain decided to return to Rose Bay to rectify faults and the landing approach was made into the north and without flaps. Finding that he had excess height, the captain introduced a left-hand side-slip during the approach. On straighening out from the side-slip, the captain proceeded with the intention of making a normal landing. On checking the glide at about 40 feet, he realized that the aircraft was flattening out too high. He stopped easing back on the controls expecting the boat to sink further towards the water. Without any further control movement the aircraft completely stalled some twelve feet above the water, dropped sharply and made contact with the water in a normal attitude but with considerable force. Impact caused a major failure of the hull which allowed extensive break-up of the fuselage. Considerable length of the rear end of the hull and tail unit separated from rest of aircraft and both sections sank within 15 minutes. Passengers and crew escaped the wreckage and were rescued but one passenger drowned.
Crew:

Passenger drowned: Mr. J. Mott.
