HOLLOMAN AIR FORCE BASE, NEW MEXICO, USA, OCTOBER 30 2012: A drone pilot, left, and a drone sensor operator practice on a simulator at Holloman AFB, where drone pilots and drone sensor operators are trained. Working side by side with the pilot, the drone’s Sensor Operator watches targets (sometimes for hours or days) and tags them with a laser just before the pilot shoots the drone’s missile (photo Gilles Mingasson for Der Spiegel).
