Robot blimp may provide wireless

Giant airships positioned 13 miles up, able to provide broadband and wireless service to a land-mass roughly the size of Texas? The first "stratellite" prototype was unveiled last April and the first test flight is scheduled later this month in the Mojave Desert. These initial tests will be tethered, and the airships will be about one-fifth the size of the real thing, according to the report. This test airship is expected to float to 45,000 feet for several hours; the real thing is expected to stay aloft for 18 months at a time.
