Two unmanned aerial vehicles (UAVs) - more colloquially called 'drones' - at Creech Air Force Base, Nevada. A General Atomics MQ-1B awaits takeoff at dawn as its larger cousin the MQ-9 takes the runway. The UAVs are controlled by nearby pilots during taxi, takeoff and landing, but while airborne they can be piloted from anywhere on Earth via satellite link.
