Sadly I think there are a number of factors to consider some have already been mentioned:
(a) The BBMF standards seem very sensible, these aircraft do not need to demonstrated to their limits, and note their currency requirements.
(b) The press seem to say the pilot was an ex harrier pilot BA captain, fine, but not in regular fast jet flying.
(c) The defendant of display pilot (PPL with 500 hours on a JP 3 (Newcastle)) claimed on media that AH must have been done to anything other than human error. Oh yes, he is apparently checked as display pilot on the Hunter T7?
(d) Previous fatality Hurricane, at Shoreham, PPL, Class two med, how can these people get approvals
