In 1940 Jack Northrop flew the N-1M, a little airplane that was nothing but a wing, off a dry lake bed in California. By 1947 his YB-49 jet bomber was one giant flying wing, and in 1949 the Air Force cancelled it. Decades later, shortly before he died, Northrop was allowed to see a top-secret design with the same 172-foot wingspan: the B-2 Spirit, which first flew in 1989. Its smooth, flat shape bounces radar away, and special coatings soak up the rest. For more facts like this, and to learn how stealth works, visit mach9.company.
