I, too, have had cause to bowl over a row of porta-cludgies, but this time by remote control.
I was given the task of marshalling incoming aircraft into the static park at a heli-meet. At the same time, a bloke from a different unit was trying to get his portaloos lined up. One aircraft was going to arrive late, and due to the prevailing wind, would have to shoot his approach over the 'facilities'. The other bloke outranked me (considerably), and wouldn't wait until the aircraft had arrived, and so I had to marshall a US Navy SH-3 directly over a row of about 20 interconnected loos.
Nobody was surprised when they all fell over in a smart and military fashion. What did cause a shock was when Officer i/c emerged from one, somewhat soiled, having decided to test his installation.
