Whilst not airborne we did have a useful trick which was used to piss off Welsh sheep and their farmers when out on Expedition Training.
L a n d r o v e r s would build up a might head of steam if allowed to coast with the ignition off. Once the ignition was switched back on there would be an almighty back fire and the aforesaid sheep would scatter to the four ends of the earth.
Great fun.
Until the day we (I) coasted a bit too long and the resulting back fire blew the silencer apart. There then followed an almighty embarrassing journey back to V bomber land through town centres and suburbia sounding like a squadron of Tiger tanks.
I learnt about L a n d r o v e r driving from that
(the spacing in the word l a n d ....etc is to stop the 'management' automatically inserting the word Trabant in its place
)
