The Mystere or Falcon 20 and 200 family remains Dassault's most successful business jet program thus far, with more than 500 built. Development of the original Falcon 20 traces back to a joint collaboration between Sud Aviation (which later merged into Aerospatiale) and Dassault in the late 1950s. Prototype construction began in January 1962, leading to a first flight on May 4 1963. This first prototype shared the production aircraft's overall configuration, but differed in the powerplant. The prototype was initially powered by 14.7kN (3300lb) Pratt & Whitney JT12A8 turbojets, whereas production Mystère 20s (or Falcon 20s outside France) were powered with General Electric CF700s. The first GE powered 20 flew on New Year's Day 1965. Throughout the type's production life Aerospatiale remained responsible for building the tail and rear fuselage. Mahogany Wood. Scale 1/48.
