I found this on avsim. It is the YRB-49, the first flying wing.
Hope to see some more shots.
That was revolutionary for it's time and in a way still is.
Nice shots of it, too bad it never became a mass production craft, there is always something better.
Cool shots PanAm - I like the second shot
Very nice shots from an interesting craft.
If you want an updated model of this aircraft, you can find it here:
This version has smoke and some more stuff.
Great plane, good pictures.
