“Lockheed rolled out its next generation HALE-D or High Altitude Long Endurance-Demonstrator yesterday for its first flight. The idea is that the HALE-D will ascend to an altitude of about 12 miles above the earth and float there in a geostationary position where it can monitor a huge patch of land and airspace. The idea is that the airship can have capabilities similar to those of satellites at much less cost.” via SlashGear
