I read the range log book at Wainfleet. It reported a bomb dropped from a Lincoln well inland of the range. When it dropped a second it was told to cease bombing. The captain then said they had found out what the problem was. They were allowed to continue and did it again.
Much more recently an F15 got a DH on the quadrant building missing the occupant by 10 feet. A few years later a Tornado did it again but missed the bomb landing only 300 yards from an ignorant bunch of spotters.
