      Emerging from Darpa's classified Copper Canyon studies of the early 1980s, the X-30 National AeroSpace Plane (NASP) was an air-breathing single-stage-to-orbit demonstrator. The NASA-led program was launched in 1986, with Rockwell becoming prime contractor in 1990. The X-30 was to be powered by liquid hydrogen-fuelled supersonic-combustion ramjets. Massively overambitious, the program was cancelled in 1993. (Photo: NASA)
