Hi Gordon W
I think that the JP manoeuvre that you describe is called a reverse stall turn in the RAF - at least that's what my student guide says. The 'noddy stall turn' was also fun - in this the aircraft is pulled to the vertical, yawed left through about 20 deg, yawed right by the same amount, and finally yawed left into a stall turn (and vice-versa). I don't think that the Hawk could do either of these, but someone may prove me wrong?
