The X-29 was built to explore 
      state-of-the-art technologies in aircraft design. The most easily 
      identified of these, the forward-swept wing (FSW) was combined with 
      advanced materials, a forward mounted elevator (canard) and an electrical 
      flight control system. The purpose of this combination of features was to 
      test how well all these elements worked together before they were used in 
      future aircraft. 
      Both Germany and the U.S. experimented 
      with FSW aircraft during World War II but did not use them operationally. 
      One problem with the new design was that the wings could not be made rigid 
      enough to keep them from bending dangerously at higher speeds. In the 
      1970s, however, composite materials became available, and wing structures 
      could be built that were both lightweight and very rigid. 
      Grumman began building the first of two 
      X-29As in 1982. The program was administered by the U.S. Air Force and 
      jointly funded by the Defence Advanced Research Projects Agency (DARPA), 
      the Air Force, and the National Aeronautics and Space Administration 
      (NASA).
