I can see for miles and miles
For years now, U.S. Customs and Border Protection has used Predator drones for surveillance flights near the Mexican border. Drones are operated by the U.S. Office of Air and Marines. The Predator drones are about the size of a Cessna airplane and provide real-time surveillance of the entire 1950-mile border between Mexico and the U.S.
The drone program has expanded over the years. NASA and the U.S. Forest Services have also enlisted Predator B drones to monitor wildfires, according to NASA.
