The first science flight took place last Wednesday and lasted for about 14 hours. The Global Hawk UAV flew for about 8,334 kilometers (4,500 nautical miles) non-stop, collecting readings with the vast array of instruments it has on board. During the flight, it reached an altitude of 18,562 meters (60,900 feet), which is about twice as high than commercial airliners. The flight was controlled from the NASA Dryden Flight Research Center, in the Mojave Desert, California.
