The twin engine aircraft was engaged in a charter flight from Teeside to Nantes, carrying two passengers, two pilots and a load of 250 kilos of cargo, including a container of Type A radioactive material weighing 37 kilos. Takeoff acceleration was normal and the pilot allowed the aircraft to accelerate to 100 mph, some 15 mph above the minimum controllable single-engine speed, before lifting off. Very soon after lift-off he felt a loss of power from the left engine but, believing this to be only a partial failure, decided to continue the take-off and raised the landing gear. He felt the aircraft was still climbing and heard the pilot's assistant say 'I have the rudder'. He then realized that the airspeed was reducing rapidly and that he was losing directional control. He lowered the nose and headed for a grass area to the left of the runway, where the aircraft struck the ground in a steep left bank. All four occupants were quickly rescued, only the pilot was seriously injured. The aircraft was damaged beyond repair.

On touchdown at RAF Seaton Carew, an undercarriage failed. The aircraft came to rest and was damaged beyond repair while both occupants were unhurt.

During an airshow in RAF Middleton Saint George, the crew was involved in a demonstration mission consisting of para-dropping a low height. On final approach, during the last segment, the airplane nosed down and crashed at runway threshold. The aircraft was destroyed and all six occupants were killed.

The crew was performing a radio navigation exercise out from RAF Thornaby. While approaching Dinsdale at an altitude of 500 feet, the aircraft was 'attacked' by the pilots of two RAF Hurricanes that were conducting an unauthorized practice interception of the bomber. To evade the 'attack', the pilot of the Warwick attempted a steep climb when he lost control of the aircraft that dove into the ground and crashed in a field. All six crew members were killed.

The crew was engaged in a night training exercise. En route, the pilot did not realized his altitude was insufficient and the crew was unable to distinguish the presence of the mountain due to the low visibility caused by foggy conditions. The aircraft hit the south slope of Mt Mickle Fell, skidded for some hundred yards before coming to rest in flames. The tail gunner was found alive while all six other occupants were killed.

Shortly after takeoff from Croft AFB, in initial climb, the aircraft collided with a flock of birds that hit the windshield. Both pilots were injured and attempted to make an emergency landing. They reduced their altitude and landed in an open field. Aircraft skidded few hundred yards before coming to rest. All crew were rescued and evacuated while the aircraft was damaged beyond repair. Crew was from 434th Squadron.

The crew was completing a local training exercise at RAF Middleton St Geroge. The airplane crashed while attempting to land on three engines, the port outer being feathered. The airplane was destroyed and all five crew members were injured. The following day, the pilot died from injuries sustained.

The airplane was engaged in a local test flight at RAF Middleton St George. It took off at 1530LT and crashed almost immediately, due to one, or both engines, failing on the port side. The Halifax climbed slowly to approximately 100 feet, stalled and dived into the ground and burst into flames. Five crew members were killed and the sixth occupant was injured.

The crew was completing a local training flight at RAF Middleton St George. While flying in the vicinity of the airbase at an altitude of 2,000 feet, just below the cloud base, a RAF Avro 652 Anson registered V4140 appeared on a converging course. The pilot tried to dive beneath the Halifax but its tail assembly caught the Halifax and both airplane dove into the ground and crashed near the airfield. All eight crew members in both airplanes were killed.
