The crash is a major loss for aviation history. First flown in 1942, Northrop’s N-9M, with the “M” standing for “model,” was a test aircraft to support the development of the XB-35 and YB-35 prototype flying wing bombers.
The N-9Ms had a 60-foot wing that was effectively a third-scale replica of the full-size bombers. This smaller surrogate design was made of both wood and metal and had a pair of engines driving pusher propellers, compared to the all-metal XB/YB-35 and its four pusher props. The N-9M was also an evolution of Jack Northrop’s earlier N-1M, which also supported the company’s flying wing work.
Northrop built four N-9Ms, designating them N-9M-1, -2, A, and B. In the late 1940s and early 1950s, the U.S. Air Force canceled the XB/YB-35 program, as well as the development of the improved YB-49. Many of the airframes associated with these projects, including the first three N-9Ms, ended up being scrapped.
