On 6 October 1972 a Buccaneer (XV339) on an airtest from RNAY Sydenham was reportedly dumping fuel in preparation for recovery when the dump valve stuck open.
When the engines wound down it failed by just a couple of miles to make the runway and crashed on a filling station in the suburbs of Belfast. There was a low-level ejection with, I believe, minimal injuries to those on board or on the ground.
