The Global Hawk recorded its first flight in 1998 and is equipped with infrared, optical radar and synthetic aperture radar. According to Ars Technica, the synthetic aperture radar can be used to locate vehicles and buildings hidden by vegetation or buried underground, and the infrared systems serves to locate people through tree cover. Facial recognition, on the other hand, may prove to be impossible.
It is unknown where the drone is based, but it is entirely possible it has to travel thousands of miles just to arrive at the area it is surveying.
Meanwhile, the use of drones in search efforts for missing persons here in the U.S. is still forbidden by the FAA, though some private search and rescue companies have decided to fight back against this prohibition.
