The pilot of the JP started the roll with the nose too low which is typical of someone either not very good or not very current. I suspect it was a bit of both. Was there extra training after the 'red card'? I'll wager the 'good old boys network' came into play and off he goes in the Hunter.
My qualifications so to speak? 3 FJ tours inc Harrier and courses on both JP, Hunter, Gnat etc etc.
He should've hung up his goggles and gone back to his A320 day job.
Finally, as I've said before, current RAF display pilots fly vastly more hours on type than these dangerous 'part timers'. Let's have a core of them to fly displays in vintage aircraft. A bit like an upgraded BBMF but with fast jets too. Properly organised and financed AND SUPERVISED AND TRAINED AND CHECKED.
