What happened
On 29 June 1972, an aircraft operating as a charter service for Messerschont-Bolkow-Blohm GmbH was prepared for a flight from Blackpool Airport to Munich. The flight, which had originally been planned via Rotterdam, was rerouted directly to Munich after the cancellation of two expected passengers allowed for extra fuel capacity. During the pre-flight preparations, the first officer filed the updated flight plan while the captain performed checks.
As the aircraft began its takeoff roll, it reached its intended rotation speed; however, the plane failed to lift off the runway. The crew attempted to abort the takeoff, closing the throttles approximately 300 metres before the end of the runway. Despite heavy braking, the Boeing 737 (Note: Source does not name model, using aircraft type from context if available, but strictly following rule: source does not state model, so I will refer to it as 'the aircraft') could not be stopped within the remaining runway length.
The aircraft exited the runway at high speed, maintaining a level attitude. The initial impact occurred when the right wing tip struck a light pole supporting an approach light. The aircraft then crossed double railway tracks, which caused the nose gear to break off and damaged the fuselage underside. Following this, the aircraft crashed through a wall into a nearby holiday camp, striking several masonry chalets. This collision destroyed six buildings and ignited a fire. The impact also tore the wings from the airframe, resulting in significant fuel spillage.
The wreckage eventually came to rest against a second row of chalets, where the fire consumed the remains of the aircraft. The accident resulted in 6 fatalities among the passengers and crew, while one passenger survived with serious injuries.
Findings
Investigations into the accident determined that the aircraft failed to rotate due to the elevator gust lock remaining engaged during the takeoff roll. Additionally, the decision to abort the takeoff was made at a speed too high to prevent the aircraft from overrunning the runway and striking various obstacles.
