spekesoftly; I watched the back-seaters abandon a Victor of either 10 or 15 Sqns on approach to Cottesmore in 1961. The Pilots both ejected safely.
I'm not sure of the height, but the aircraft was configured for landing with everything down that should have been down, and it ended up in a paddock on the other side of the A1 from Cottesmore, at about 3miles. 1000' perhaps?
According to Air Clues, the aircraft had a fuel transfer problem which caused all four donkeys to stop, but the report also noted that this had been the first Victor accident where all five crew had survived.
