I was one of the pilots in the Sea King from RAF Boulmer that responded to the crash site (one of my first, if not the first callout of my career). IIRC it was a low level abort in bad weather that went tragically wrong. The crash site had such a limited spread of debris that it seemed like the aircraft must have been near vertical when it hit. Very low cloud base in the area, maybe a couple of hundred feet, if my memory is correct.
