It said: “One half of the structure is fully involved in fire and the building has suffered a significant structural collapse.” The fire service added: “We have 15 fire appliances, and three specialist aerial appliances from across the county and surrounding counties in attendance and this has been declared a major incident by Bedfordshire fire and rescue service. “Fire crews are working to extinguish the fire and prevent it from spreading to adjacent buildings and vehicles on air side of the airport.

He told the PA news agency: “There were a couple of fire engines with a car ablaze on the upper floor of the car park at just after 9pm. “A few minutes later most of the upper floor was alight, car alarms were going off with loud explosions from cars going up in flames. The speed in which the fire took hold was incredible.”
