Ford flying high with futuristic Boeing UAV
Boeing is reporting progress in simulation tests of its HALE (high altitude long endurance) aircraft, an unmanned plane that runs on hydrogen.
While it has not yet gone aloft, the propeller-driven HALE aircraft was able to run for a total of three days in a chamber that simulated flight at 65,000 feet. The eventual goal is to get it to fly for more than a week at a time with a one-ton payload.
