I believe most losses were due to the engine stopping, the aircraft operating down to 100 feet which was bird strike territory...thankfully Martin-Baker provided a great ejection seat! We had a few different aircraft losses that weren’t engine related, one chap flew into the ground at night and got ejected, one where the flaps stayed down as the nozzles move back after take off, pitching the aircraft forward onto its back, the pilot ejected and is still the sole survivor of this type of event..
