while helicopters cannot be used to rescue people in a fire zone given the wind it creates while hovering that fans the fire (my guess), what if we use 6 to 8 drones that can hover away from the fire zone with 6 or 8 ropes tied in the middle to rescue one person at a time.
such drones are easy to manoeuvre while GPS provides the exact position of the fire zone and flying paths, with the distance among them remaining constant.
