Very cool museum; they have some incredible stuff. However, the "Blackbird" you mention isn't actually an SR-71, it's an M-21 - a variant of one of the CIA's A-12's (the SR-71's predecessor).

If you're in Seattle and have an opportunity, visit the Museum's restoration facility at Paine Field in Everett (at the opposite end of the runway for the 747/widebody factory.) It's a nondescript warehouse manned mostly by super kind volunteer retirees. Unlike the roped-off museum experience, at the restoration facility you can touch and pick up things. The last time I was there I held a Merlin piston in my hands. So cool.
