I was both a Hunter and Hawk QFI in the early 80s. I have about 1,000 Hunter hours including 65 sorties on WV372 (bit miffed that ‘my’ jet has been trashed). Looped probably thousands of times. MRTs in the Hawk were ‘pull 6 squeeze 7’ initially then ‘pull 5 squeeze 6’ when it was thought that we might use too much fatigue. We received (and gave) plenty of training on the safe application of high G, both rapid and gradual onset, although expressions such as ALoc and GLoc were probably not in the vocabulary. So I am puzzled that possible incapacitation from high g should be used as an argument by the defence team, especially in a Hunter at 300kts when you're likely to hit the buffet before 4g. Also, it appeared to me that the aircraft was under positive control for the last half of the loop (and it was a loop).
