    deglr6328 writes "NASA's solar powered Helios airplane has crashed into the Pacific off the coast of Kauai today during its first test using a regenerative fuel cell power supply. Helios held the record for highest prop propelled plane altitude at 96,863 (set 2 years ago) and was making preparations for a 96 hour continuous flight using its 62,000 solar cells during the day while electrolyzing water into hydrogen and oxygen for use in its fuel cells at night. With the capability to carry 200 lb. to near 100,000 ft. for months on end, Helios was eyed with great anticipation by scientists and RF telecommunications buisnesses alike."

    Brussel writes "SkyTower in collaboration with the Japan Ministry of Telecommunications (CRL/TAO) and NASA has successfully completed a series of commercial telecommunications tests -- the world's first from more than 60,000 feet in the stratosphere. The tests, which began three weeks ago, were conducted from Pathfinder-Plus, an unmanned solar-electric aircraft developed by AeroVironment." There's another press release here.
