At 1839 hrs on the evening of the accident, a Vickers VC.1 Viking twin-engined airliner of BEA (registered G-AHPN and named Lord St Vincent) took off from Le Bourget Airport

 in Paris on a scheduled flight to Northolt airport, London with a crew of four and 26 passengers. A weather forecast obtained before the flight took off had warned of poor visibility, and about 45 minutes after departure as the aircraft neared London, British air traffic control (ATC) informed the pilot that fog had reduced the visibility at Northolt to 50 yards (46 m). On receiving this information, the pilot announced that he would attempt to land at London Airport instead. Although visibility at London Airport was only 40 yards (37 m), it had the facilities for a Ground-controlled approach

 (GCA, i.e. a "talkdown" by radar operators). The pilot told ATC that if he could not safely land at London Airport, he would divert to Blackbushe Airport

The aircraft carried out what appeared to be a normal GCA, reaching the decision height of 140 feet (43 m) at about 400 yards (366 m) from the end of the runway. Shortly after reaching this point the pilot announced over the radio, I am overshooting (aborting the landing attempt and carrying out a go-around

), but a few seconds later the aircraft struck the runway and skidded along it for 140 feet (43 m) before regaining the air. With both propellers damaged by the initial contact with the ground, it finally crashed approximately 3000 feet (914 m) further along the runway, the starboard wing being torn off and the aircraft bursting into flames as it came to rest next to a store of drain-pipes. The thick fog hindered rescue attempts and it took the fire and rescue teams 16 to 17 minutes to find the crashed aircraft. Of the 30 people on board there were only two survivors, a stewardess and a passenger; both had been seated near the tail.

Lord Brabazon reported first, in February 1951, making a number of recommendations regarding the lighting of airfields in poor weather conditions, the measurement of visibility and the setting of minimum weather conditions for landing. While the accident report could not establish for certain the precise cause of the accident, it concluded that the pilot had probably intentionally descended below the decision height, only aborting the landing when the aircraft entered the fog bank at an altitude of less than 100 feet (30 m). Alice Steen, the hostess who had survived, had reported to the accident inquiry that the pilot Captain Clayton came back into the cabin and told her that they would not be landing at Northolt but at London Airport instead where the visibility was 400 yards (366 m); it was noted by the inquiry that Clayton had been told 40 yards (37 m) on the radio. It was also noted that BEA's operating manual was confusing as to whether the decision heights stated were compulsory or advisory only, and Monckton recommended that aircraft be prohibited from landing where the visibility was significantly below the minimum conditions set by the operator. The recommendations of both Brazabon and Monckton were all implemented.
