so instead of winching, what about lifting a big solid basket type thing onto the heli deck. people walk in, far quicker than you can winch, then haul them off to the nearest bit of ground where they can be unloaded and then shuttled from there by other helicopters. you would get the pax unloaded way faster than winching.
Yes they are on a hook, but put a safety strap through the body and get into it.
