And what the hell does a flying wing have to do with stealth technology.
Pretty much nothing, though Wikapedia is spreading the old rumor again I see. Though the B2s airframe owes homage to previous Northrop efforts B-35 in particular, in reality the reason both the B2 & the cancelled A12 used the type of airframe is tests done on the SR71 and its variants during the Vietnam war, until it turns a 71 is virtually invisable. In addition, the F-117, a much more successful stealth aircraft is based all on Russian Mathematics that were probably accidentally published. Ben Richs book has that and alot more if you are really interested.
