Went to RheinD as a 'helper' as an OTC cadet for Ex Lionheart. With a couple of mates though it to be a great idea to go down a line of Landies that the Hofficers had parked up for a meeting and turn the underseat fuel tank taps to the mid position. Meeting ends, and a line of Landies conk our about 300yrds down the road......tsk tsk...student humour!
