well maybe,here is a link to a BBC news video.
in short, in Australia they are working up a way to get supply's,in this case water,to a lost person in the Outback using small drones.needs some work but i could see how the fast delivery of survival gear to a lost or trapped person this way would save time and the hassle involved in a air drop by a large aircraft.
