A passenger jet carrying 168 individuals faced a significant safety risk last year after its pilots made a critical error during take-off from Luton Airport. An investigation by the Air Accidents Investigation Branch (AAIB) revealed that the Boeing 737-800, en route to Athens, Greece, lifted off just 162 metres from the runway's end and was only 13 feet (four metres) above the ground as it crossed that point.
The incident, which took place on April 22, 2025, involved 162 passengers and six crew members. The AAIB's report concluded that the pilots failed to correctly adjust the settings on their flight management computer (FMC). This crucial oversight occurred because they were instructed to depart from an intersection on the runway, rather than utilising its full length, but did not modify the aircraft's systems accordingly.
This error meant that the maximum thrust generated by the aircraft was lower than required for the reduced runway distance. According to the AAIB, this created a dangerous scenario: "If the aircraft had suffered a loss of thrust during take-off, there was a potential that it would not have been able to stop on the remaining paved surface following a decision to reject the take-off or, alternatively, achieve minimum height clearances during departure following a decision to continue the take-off."
Airliner pilots are mandated to input specific thrust settings into their onboard computers prior to take-off. These settings are vital to ensure the aircraft has sufficient runway remaining to stop safely if an emergency requires an aborted take-off, and to guarantee it reaches a minimum height to clear any obstacles beyond the runway's end.
The flight involved in the Luton incident was operated by Ascend Airways. The company, which had its headquarters in Bishop’s Stortford, Hertfordshire, specialised in 'wet-leasing' – providing aircraft along with pilots and cabin crew to other airlines. Ascend Airways ceased operations in April 2026.
