I was once sitting in the back seat of a C172 parked facing up a bit of a slope. For some reason mein Kapitan released the handbrake before start up and we started to roll backwards towards the clubhouse. He applied the brakes quite heavily and, no doubt assisted by 200lbs of yours truly perched aft of the centre of gravity, we came awfully close to ploughing a narrow furrow with the bottom of the rudder! Not an auspicious start to a jolly...
The C-17 demo at Farnborough one year included a reverse thrust exit from the runway followed by some enthusiastic braking and a distinct lifting of the nose gear! The crowd loved it.
