People have been discussing ejection again, which leads me to a question.
A couple of weeks ago, during the discussions following the Gnat crash and subsequent untimely passing of pilot, Kev Whyman (RIP), it was mentioned that civilian operated fast-jets are unlikely to have a live ejector seat, due to the costs involved in maintaining them, the availability of spare parts (which is a significant problem with vintage aircraft), the costs to insure aircraft with live ejector seats (not to mention, the problem of getting the CAA to approve it in the first place) and the possible lack of access to adequate training facilities to maintain ejection currency.
This was a civilian owned airframe, right? So perhaps the Pilot didn't have the luxury of live firing handles between his legs so couldn't eject after realising the aircraft was doomed, so didn't even attempt to (hence why the canopy didn't jettison).
It has been reported that he once flew Harriers operationally in HMF, so with a good background flying fast-jets, why wouldn't he eject if he was able to?
