NASA’s Helios may be the next new-fangled solution for “last-mile” broadband. At 1,850 pounds it can take off at an amazing 30mph, fly at an altitude of 100,000 miles, and recharges with solar power. Subscribers would use a satellite dish for access. Most surprising? “Helios’ ‘brain’ is an Apple Computer Macintosh computer.” Our skies could be layered with all sorts of transportation and telecommunications equipment soon.
