Hi Chevvron
I also had an ATC camp flight in a Provost, at Shawbury in '58. half an hour in the instructor announced 'Keep it straight and level fo a couple of minutes', produced a sick bag, and peed copiously into it; slid back the cockpit to chuck it out, announced 'I have control' and wound it into a tight turn to see if he had hit a target. Shortly after he spotted a Chipmunk and we snuck up behind and below, until after a few minutes he spotted us. A Chipmunk can definitely beat a Provost in a tight turning mock combat. F2
