On November 6, 1957 at 12:00 AM, Bristol - Bristol experienced a crash involving Bristol Britannia, operated by Bristol Aeroplane Company, with the event recorded near Bristol-Filton Gloucestershire.

The flight was categorized as test and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) crash site.

15 people were known to be on board, 15 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.

The listed crash cause is technical failure. The Bristol 175 had just completed a test flight of 1 and 40 minutes. Tests included a strain-gauge measurements on the non-standard propeller of the no. 2 engine, and high speed upset manoeuvre recovery tests in connection with the US certification. Returning to Filton, the aircraft entered a circuit and partial gear extensions occurred for unknown reasons. Attempts may have been made to complete undercarriage free fall tests as these had failed the previous day; such test were not on the programme however. At 1500 feet a left turn to base leg was initiated. The right wing suddenly dropped and the aircraft went into a very steeply banked right hand turn. The Britannia briefly recovered but banked steeply again and struck the ground in a wood near a residential area.

Aircraft reference details include registration G-ANCA, MSN 12917, year of manufacture 1956.
