Back seat driver
A very similar thing happened to a Hawk a while ago - on arrival at a 'field ( forget which ) he threw in a few rapid rolls at low level - snag being when he decided he'd made enough of an impression the plane kept in the rapid roll...
Story was that the apron on the rear seat had been insecure, whatever it was caused a control restriction -
It was said the pilot pulled the handle while inverted, reasoning he'd be upright as he left - he was right !
No injuries to anyone as far as I know.
