Boeing this week unveiled its latest UAV, the hydrogen-powered Phantom Eye, which the company says will stay aloft at 65,000 feet for up to four days. "The capabilities inherent in Phantom Eye's design will offer game-changing opportunities for our military, civil and commercial customers," said Darryl Davis, president of Boeing Phantom Works, at the introductory press conference in St. Louis on Monday. The demonstrator is powered by two 150-hp engines and has a wingspan of 150 feet. It will cruise at about 150 knots and can carry up to a 450-pound payload. The aircraft will be shipped to NASA's Dryden Flight Research Center at Edwards Air Force Base in California later this summer to start ground and taxi tests, with flight tests expected early next year. The first flight is expected to last for four to eight hours, Boeing said.
