On 7th November 1957 I was scrambled at Chivenor to search for a chap who had ejected from a Hunter whilst air/air firing off Hartland Point. The tug pilot had seen him eject but didn't see a parachute. I saw nothing of note and he was never found. However a considerable number of the OCU's aircraft - if I remember correctly more than twenty - were subsequently discovered to have the drogue gun projectile lanyard incorrectly routed such that it would probably have clobbered the ejectee and was considered to be the likely cause of the fatality.
