They Thought They Were at 11,500 Feet - Christmas Eve Crash Mystery
Fear of being inches from death in plain daylight: a Bristol Britannia 312 on a routine test flight descended believing it had 11,500 feet beneath it when it actually had 1,500 - a ten-thousand-foot error that left nine dead and snapped telegraph poles like matchsticks. How could two trained crew, working instruments that functioned correctly, misread a single dial with such catastrophic consequences?
In this episode, we tell the story of that Christmas Eve flight and the chain of ordinary events - fog, a diversion to Hurn, a routine airworthiness check flight from Heathrow - that combined into disaster; we follow the wreckage trail across Burley Road and the questions investigators had to answer: what led a functioning aircraft and professional crew to collide with the ground?
Person: Nine fatalities on board
Date: 24 December 1958
Aircraft: Bristol Britannia 312, registration G-AOVD
Departure: Heathrow Airport at 10:10
Clearance: Descend from 12,000 ft to 3,000 ft toward Hurn
- The crew were cleared to descend from 12,000 feet to 3,000 feet but the aircraft was actually at 1,500 feet when descent began.
- Visibility was reduced by a dense, low maritime fog across southern England, making fog visually indistinguishable from cloud from above.
- The flight was a non-revenue airworthiness renewal test flight with twelve people aboard (seven in the cabin, five crew).
- Telegraph poles along Burley Road were snapped at the base, their wires dragged across the frozen ground marking the wreckage path.
- G-AOVD lifted off from Heathrow at 10:10 and contact with Hurn was noted at 11:58; three minutes later there was no further contact.
