The winch-operator/technical crew member in the door should have directed the pilot to descend and also winched out to increase the distance between the stretcher and the downwash - maybe they don't talk to each other much!
A simple 5 -10 knot hover taxi would also have minimised the spin.
Serious question Crab, why get the helicopter to descend? I'm experienced in winching operations and did not consider than an option. I'm interested to know why you think it is?
The winch out goes without saying.
