The Horten Ho-229 (often called Gotha Go-229 due to the identity of the chosen manufacturer) was a German prototype fighter/bomber design approved by Göring late in WWII and is recognised as the first pure flying wing powered by jet engines. This is the only surviving Ho 229 airframe, the V3, and is now awaiting restoration at the Mary Baker Engen Restoration Hangar at the Udvar-Hazy Center. Note the that T2-490 code was attributed by the Office of Air Force Intelligence after arrival in the US.
