HX-2 'Flying Wing' By Horten Aircraft A 'Flying Wing' in 2019? Yes, a prototype flew to the recently held AERO Friedrichshafen in Germany. It is called the HX-2 by Horten Aircraft. Of course the flying wing is not a new concept as this one pays homage to Reimar Horten from his exploits in the World War II era in regards to the fuselage-less winged aircraft. They only have managed to do a few flights totaling 6 hours in flight testing so far.
