Another guy who underrates the genius of Jack Northrop explaining, for no good reason, that not only Northrop’s eponymous Flying wings (YB-35/YB-49) but even nowadays B-2 are in essence “Horten’s stuff”.
Northrop and the Horten Bros were almost contemporaries, the classic case of parallel development. Jack’s first timid steps into the flying wing universe were made in the late 20’s with the X-216H. By the time this delicious experimental testbed flew (1940) Northrop felt sure enough: it was his first truly flying wing aircraft. Anyway, there was still a lot of work to do and the N-1M was just the first real step into the development of Northrop’s quest.
Good to know this gem is so lovely preserved in the National Air and Space Museum’s Steven F. Udvar-Hazy Center
