Someone posted a short film some years ago of a stretcher hoist gone very wrong….it was spinning at very high RPM with the patient strapped in and the paramedic hanging on for dear life. Funny to watch but not so funny for the folks involved.
There was also the one where a stretcher was lowered to a wildly pitching deck of a small fishing craft ….they unhooked the stretcher and headed below to get the patient. A seaman still had the hook in his hand so he snapped it onto the rail ( Don’t want to lose this!) …turned and rushed below leaving the deck deserted and the helicopter firmly moored to the ship. The crew had some fun maintaining station while until the patient was brought up on deck. I would have luved to have heard the audio on that one.
