Not an FE but interesting enough. At Pompano after completing a straight in auto to power recovery there was a snap sound and a buzzing that I had never heard before, and cyclic shook somewhat.
We had evidently picked up a large foil bag (of what I don't know) on the main rotor.
Eng and Nr were ok, so I announced I was setting down. I set down and we had to de-clutch to slow the system to where we could get the thing off.
No big deal but having it happen to you gives you a good idea of how you shall handle something not experienced before, Mark had told me of several people he knew (past tense) who would freak and do the wrong thing, I had heard the noise, saw the reaction of the craft and evaluated it, then took steps. just what one needs to do in a real IFE.
