Michael Smith ...!{hplabs,ihnp4,amd,nsc}!amdahl!ems 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.
