I recall over twenty years ago, a certain Flight Lieutenant, then serving as a QHI on 240 OCU, being tasked to fly a great big, brand new, air portable SatCom station for the British Army. I think it was the first they ever had and obviously an extremely expensive piece of kit. It was a large, heavy "Portakabin" type shed on wheels. As the Chinny transitioned away, it suffered an engine "cough".
The obvious resulted........ load jettison button was pressed. The Chinook crew returned home, hugely embarrassed for busting the Army's new toy.
Oh, how we simple Puma folk sympathised!
The Army later sent some reminders in the form of photos of the scene - IIRC, the largest recognisable piece was the jockey wheel off the front of the chassis
But said Flt Lt got his own back by being stratospherically promoted to Air Rank.
