According to Theodor von Karaman, probably the greatest aerodynamicist 

going, the Northrop Flying Wings were excellent for low-speed flight.  

However, at the time, the Air Force was looking for aircraft with a

thin wing section fo transonic/supersonic flight, and the Flying Wing

*had* to have a thick cross-section.  Please note that the N1M was under-

going tests in the late 30s; it's not surprising nobody was concerned 

about transonic flight.



From what I've read, there also was a political (DoD) decision on 

discontinuing development on it.



A few people made Flying Wing homebuilts, but they're .. interesting 

aircraft to fly.  The stall characteristics are gentle, but if you put 

one into a spin, watch out!



But one great advantage of a Flying Wing was that the lift was 

distributed across the entire surface of the aircraft (*all* of it was a 

lifting body, after all), so the internal (structural) stress per 

maneuver was less than with an aircraft with a conventional fuselage.
