Northrop-Grumman sponsored the construction of a full-sized(?) Ho229 replica back in 2008 to test its stealth properties
The National Air & Space Museum has moved its 229 into the restoration hall to start work. Finally.
I toured the Paul Garber facility, oh about 20 years ago, and stood right next to the wingless Ho 229. What an aircraft. Also, got to see the Northrup N-9MB fly at the Chino Airshow, back in maybe the late 90s.
The Horten brothers’ work goes back well into the early 30’s when they were just kids.
