The UAV makes the technology available to the typical SAR operation at a relatively small cost. In 1980 I was ivolved in what became a very high profile search for a missing Park Ranger (Paul Fugate) in Chiricahua National Monument, Arizona. We got assistance from the Air Force and they flew in a helicopter with equipment that they could not discuss and told us they could find no sign. It was definitely not standard practice at the time. Contrast that with the current situation, a sign of things to come. the cheap, accessible UAVplatform will really make a difference.
