Was Number2 to the Sqn Cdr (Bunny A)while on det to Alberta with 4 Pumas. Task was to take Army boss to a curry lunch. This was all set up in a very large marquee. Sqn Cdr makes his approach to very close to marquee - this inflates with air, pulls all the stakes/pegs out. Sqn Cdr bogs off rapidly. Marquee collapses onto assembled throng, knocking the food onto the floor as it did so. Sqn Cdr borrows dog collar from the padre and goes back by road.
He did survive.
