Boeing is readying its hydrogen-powered Phantom Eye unmanned air vehicle demonstrator for first flight following the completion of taxi tests at Edwards AFB, Calif. The testing, which included a high speed taxi run down the centerline of one of the runways at the base’s dry lakebed, concluded on April 21. The company adds that the 150-ft span vehicle achieved “all required test points in its preparation for first flight.”

As my colleague Graham Warwick noted recently, Phantom Eye is powered by a pair of Ford truck engines modified to run on hydrogen and triple-turbocharged to operate at high altitude. Phantom Eye is designed to stay aloft at 65,000 ft. for four days, as a precursor to a 10-day-endurance UAV.
