One Week Aloft

From AVWeb:
AeroVironment Inc. announced Tuesday that it has successfully flown at Edwards Air Force Base its Global Observer drone, a hydrogen-fuel-powered unmanned aircraft sporting a 175-foot wingspan and one-week-long endurance. The aircraft's internal-combustion engine burns cryogenically stored liquid hydrogen
The drone is designed to cruise at 65,000 feet and carry a telecommunications package to enable no-delay communications relay over a 600-mile diameter. With a one-week endurance burning frozen hydrogen, it tucks away above most air traffic, silently replacing satellites. Neat technology.
