People are acting like a personal drone 1 ft across is going to pick up a case of IV fluids and deliver them across a mountain. A whirlybird of MASH show could carry a pilot and 2 patient on the outside of craft (600 lbs). To make a chopper drone to haul any real load in an Emergency you will need one the size of a Huey of the Vietnam era. You only need one pilot on that mission. It will be safer he can drop it in a remote are or try to land and even haul out a critical patient.
