The X-34 demonstrator is shown being taken out of its hangar and placed on the tarmac. The X-34 was classified as part of the Pathfinder class demonstrators which include small experimental vehicles or less expensive flight experiments. These demonstrators were driven by technology and were executed every one to two years. They were done quickly, for low cost, and for a wide range of technologies and applications. The X-34 program was cancelled in 2001.
