I wasn't in the aircraft but back in the mid nineties one of our Sea Kings was getting fuel on a Nimitz class US carrier. When they lifted off to depart they moved off over the side, lost ground effect and when they pulled more power the collective jammed. So, they disappear over the side of the carrier and the air boss hits the crash alarm...
the Navigator jumps out of his seat behind the pilots and finds the problem. It was common for us to hang our helmet bags on the opposite pilot seat so we could retrieve various bits in flight. The copilot had his flight publications in his bag and one thick but small book had jammed between the collective and the seat.
Happily it is a long way down from the deck of a carrier. You can imagine the message traffic...LOL oops.
