Actually, If you go to Udvar -Hazy and look at the Northrop P-61B and the N9M flying wing parked in front of it, it is shocking how primitive the Northrop designs are. Go up on the walkways and look down at the aircraft from different angles. The Northrop is very crude compared to the Horten designs. The Horten designs obsess over efficiency, and airflow as it moves across the aircraft. According to Wikipedia, The Horten brothers worked together with Professor Lippisch. First guy to design a flying wing. There is a Lippisch flying wing in the restoration center you guys havven't even mentioned. It's painted white.
The N1M was designed to test different wing sweep angles, hence the fit of certain components wasn't always optimum.
The Horten 229 was a 1944 design.
"The N-1M was one of a progression of experimental aircraft that further developed Northrop's all-wing concept. The aircraft was produced in the United States and was developed during 1939 and 1940 as a flying testbed for the purpose of proving Jack Northrop's vision of a practical Flying Wing. Built mostly of specially laminated layers of glued wood, the design of both wooden wings allowed for easy configuration changes with the central blended fuselage, which was made of tubular steel. The diminutive, twin-engine test aircraft served its purpose well, first taking to the skies on 3 July 1941 at Baker Dry Lake in California."
Northrop had actually first started work on a flying wing design in the late 1920s.
