"A Pax in an RAF FJ aircraft should not be placed under a "G" loading of 6.5 and the rules are explict on this. The limit is 2/3rds of the last value."
Really - take a 21 year old SAC Liney ... me, 1 Group Captain (not far from promotion and leaving the station) and a Hawk needing a full air test. Up to 44,000ft …. Mach 0.98 downhill …. 4 turn spin to the right … 4 turn spin to the left ….. whilst trying to write down figures from the front seat and throw up at the same time. Fly it from the rear seat, cycle gear / flaps etc. Down to low level, 8g somewhere near Llanwrst – ‘that really hurt’, out to sea low level max chat, test airbrake into circuit and land.
Trip time 59 minutes, had to be helped exit the jet, felt ill for 4 days. 
That is exactly as I remember it, it was 1991 and I hope the limits quoted above are enforced to stop young men thinking they can handle anything ‘old man – harry staish’ can throw at them.
If you are out there, Ex Gp Cpt Andy Griffin thank you, it was one hell of a first, of many, fast jet trips.
