On August 13, 2001, [1] the Helios Prototype piloted remotely by Greg Kendall reached an altitude of 96,863 feet (29,524 m), a world record for sustained horizontal flight by a winged aircraft. [4] The altitude reached was more than 11,000 feet (3,400 m) — or more than 2 miles (3.2 km) — above the previous altitude record for sustained ...
Over a four-year period, a total of $192 million was spent on the project, with NASA contributing $109 million, the U.S. Air Force $16 million, and Boeing $67 million. In late 2002, a new $301 million contract was awarded to Boeing as part of NASA's Space Launch Initiative framework. [6]
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
NASA one was a Gulfstream G-III with a seating capacity of 12 people. The jet is stored in an FAA hangar along with 3 other government planes. [32] NASA now shares a plane with FAA.

The aircraft had previously made 16 flights with stiff wings to prove its operating envelope. [7] The second X-56A unmanned aircraft flew for the first time on 9 April 2015 while under operation by NASA. [8] The aircraft flew eight flights with the stiff wings to clear its operating envelope. [9]

These high-altitude side-looking cameras, secured by a roll-stabilized mount, could take oblique shots at 5 to 15 degrees below the horizon up to 60 nautical miles (110 km) range from the aircraft and provide 30-inch (76 cm) high resolution images. [5] The electronics were also updated on the standard F model.
The Hawk30 flying-wing is a development of the NASA Pathfinder and NASA Helios high-altitude, long-endurance unmanned aircraft built by AeroVironment for NASA. [2] Resembling the 1999 Helios, the tailless aircraft is a 256 ft (78 m) span flying wing with 10 electric-driven propellers. Orbiting at 65,000 ft (20,000 m), it is solar-powered by day ...
