Boeing’s Phantom Eye technology demonstration aircraft climbs into a cloudless sky over Edwards Air Force Base after takeoff from Rogers Dry Lake on its second flight, Feb. 25, 2013. The 150-foot wingspan aircraft, powered by two hydrogen-fueled internal combustion engines driving slow-turning propellers, is a prototype for a future long-endurance intelligence, surveillance, and reconnaissance aircraft that would be capable of remaining aloft for up to four days.February 25, 2013
