I have vague recollection of an exercise in, I think, 1978. Possibly a Mallet Blow ? I watched the height finders at Boulmer nodding up & down, then a colonial F111 came thundering across the site at uber low level and a Hunter jumped it over Lynemouth Bay. I reckon the Hunter claimed the kill, but Boulmer was probably counted as being compromised in the process. I think the Hunters were based at Newcastle Airport for the exercise and were from TWU.
