X-15 Spacecraft Under Construction For US Air Programs
The X-15 hybrid aircraft is being built in Los Angeles for the Air Force Navy and NACA. It will launch by rocket and glide through a ballistic arc reaching hypersonic speeds with a nickel alloy external skin and titanium inner lining. After initial tests responsibility will pass to the Air Force and NACA to study high speed friction heat and external atmosphere control while also examining pilot weightlessness effects.
