Limitations and all, Down East is now the first civilian entity of its kind to receive an FAA exemption for search and rescue. Down East already has a helicopter, a propeller-driven manned airplane, and a variety of all-terrain ground vehicles. The drones will fill a niche, allowing flights in places where airplanes and helicopters can't go. They can also stream video to rescue workers on the ground in flight, rather than recording it and processing it later. Besides their sensors, the drones can carry a small amount of other cargo, so they could potentially deliver medicine or supplies to trapped hikers.
