Yeah. I distinctly remember that part too. Whole damn plane is made from titanium. Heats up and expands and seals itself. Reminds me of something my brother-in-law in the aerospace industy said once, "It's less like flying a plane, than it is a collection of 250,000 parts all flying in close formation". He wasn't talking about the SR-71, but it still fits. It is a prodigious feat of engineering. And it looks like a Star Wars prop from the reject pile--"Naw, they'll never believe it." Then they go and make the Princess' ship from Naboo (whatever NOT a starwars geek, merely an admiring amateur) ggrr. this one
Is that a blatant SR-71 ripoff or what? Maybe "homage" is the right word.
