Boeing is planning to run test flights of its company-funded Phantom Eye hydrogen-fuelled long-distance UAV (unmanned aerial vehicle) in California in late October or early November.

The vehicle, announced and first tested in July 2010, is twin-engine with a 150-ft. wingspan and cruises at approximately 150 knots. The upcoming flights aim to demonstrate up to four days flight endurance at 65,000 ft.
