High Altitude

Base jumper aims to break sound barrier in free-fall.

A new record has been set for the highest airship flight, with JP Aerospace's Tandem twin-balloon airship reaching an altitude of 95,085 feet (28,982 meters).

The Global Observer unmanned aircraft has taken to the skies for the first time using hydrogen-fueled propulsion.

As part of the second phase of DARPA’s Vulture program, Boeing will develop a full-scale solar-powered demonstrator called the SolarEagle that will make its first demonstration flight in 2014.

With a wing-span of 150-feet, the hydrogen-powered aircraft will cruise at 150 knots, carry up to 450-pounds and stay aloft at 65,000 feet for up to four days

Boeing has achieved a milestone in the development of its High Altitude Long Endurance (HALE) unmanned aircraft by successfully testing a hydrogen propulsion system in simulated conditions of 65,000 feet.
