> SR-71 was designed on paper and turned out amazing Well, "amazing" is relative - it was a hastily constructed leaking bucket of kerosene, and within the first five years of its first sorties, one third of the planes have crashed and burned. Not even Lockheed's other famous death trap - the F-104 Lawn Dart - was as dangerous as the SR-71. (And of course the F-35 is supposed to be doing every single job under the sun rather than having a single purpose - hence it being outperformed by its Chinese single-purpose carbon copies already.)
