The SR-71 is one of my favorite aircrafts ever. It's just so freakishly stylish. If you pictured something that can break the sound barrier and then some, that's what I picture.
I just realized that the jet from X-Men: THe Animated Series looks an awful lot like a Blackbird..
It was bizarre to see a Minuteman rocket there. I knew those were huge, but I had no idea HOW huge. It's rather scary to think that that could very well have been a nuke at one point in time. In comparison to Fat Boy and Little John, the amount of damage that a nuke that size could do is absolutely frightening.
I totally nerded over everything Space related there. I'm definitely dumb when it comes to identifying machinery and knowing what they do, but I love learning about stuff that's been in Space and back. There was an unmanned plane from NASA there, and if you looked inside the window, you could easily make out someone's email. Someone else said "If found, please call ###". The NASA engineers had a great sense of humor. You can really sense their well-wishing on that craft.
Spruce Goose, yeah. Very, very impressive. While it is definitely just this awkward, weird plane that barely flew, it's really a great feat of engineering, I think. I got to touch it before it was reassembled at the museum since a family friend of my cousin's stored the wing flaps of the Spruce goose in their warehouse. I couldn't fathom that what I was looking at, these giant wooden slats that stretched many feet down this warehouse, were only a PART of the wing, not the wing itself. Seeing it all put together in person was definitely a worthwhile experience.
Did you climb in the B-12 bomber? It's so cramped! That thing definitely earned its nickname "Flying Fortress".
Jaybug, I think if you haven't already, definitely visit the Seattle Museum of Flight. They've got the 1960's-80's (I think) Air Force one plane that you can climb through, the Concord, another Blackbird, as well as many, many others. They've even got the first biplane from Italy. It's definitely worth a visit, but you'll need a good couple of hours to get through everything. The place is huge!
