I think the SR-71 Blackbird is just about the most amazing object there is. This story provides an interesting look at actually flying one.
The Museum of Flight at Boeing Field in Seattle has an M-21 Blackbird, an earlier variant of the SR-71. I think it's worth the trip just to look at this airplane. It's one of those things that I could just stand and look at for hours.
You can see from the picture in the SR-71 article how crazy, confusing and old the controls are. How the hell would you fly the thing?
