Logic Bomb writes: "Mach 5 -- 5 times the speed of sound, or 5000 mph -- is a speed that so far has eluded jet-powered aircraft (the existing record for a production craft is about mach 2.1).
Umm, while the Blackbird (SR-71)'s top speed is classified, most knowledgeable folk put it between Mach 3.1 and Mach 3.3.
Also, there are always those fun tales off liquid hydrogen tanks at Lockheed, and C5's loading strnagely shaped waveriders.

| Presumably the guesses of "knowledgeable folk" about classified accomplishments don't count towards a record.
"Gee whiz, Beav, I'd guess you were goin' a hundred miles an hour on that bike by the time ya got ta the bottom o' the hill!"
"Wow, I musta broke the record! I'll write those Guinness people as soon as I get outta this gosh-darn body cast!"
"But, Beav, then your Mom might find out about ..."
"Aw, shucks."

textbooks.
Ie., given a certain inlet spike geometry, figure out the greatest Mach number that will keep the mach cone from infringing on the inlet.
The F-104 (also by Lockheed) had a nifty convex inlet curve to allow lots of little compression shocks.
But this is all probably over your head.

Yup. (Yes, folks, isn't it astonishing!? Someone posting to Slashdot who actually admits that he doesn't know everything! Wow! Better mod this up!)
But "people who read aerodynamics textbooks" are still guessing, no matter how knowlegeable those guesses are. Educated guesses about classified perfomance is pretty much irrelevant to "the record". By definition, any such flights -- if they happened -- are off-record.
