I had the treat of a personal after hours tour of the assembly floor at Lockheed Martin in Ft.Worth where the F16 is built. My cousin is a big wig there, and took me around with nobody else present a few years ago (pre 9/11). What a trip...there is soooo much stuff packed into those planes it would blow your mind, and the tooling on the assembly floor is unbelievable...
The next craziest thing I have ever seen is the JSF/F-35...400' takeoff, go Supersonic, hover 100' in the air and land vertically...
