Happened with an F-4 out of Leuchars when I was an FA at Buchan. BOI assumption was that he mistook the haar for another cloud layer and that the target was below.

Also happened with an F-3 out of Leeming when I was at Boulmer. Nav ejected in time, pilot left it too late and, IIRC, was found in the water with a deployed parachute.

I also recall the story of the Lightning who got disorientated whilst chasing a high level evading target and found himself in a vertical descent passing M1.3. Closed the throttle and pulled the stick back and waited. IIRC he blacked out as G increased and came to with the altimeter climbing through about 300ft, recovered and brought home a severely bent airframe.
RIP to the deceased in each case.
