The "Technik Museum Speyer" has a large collection of, well, everything. That includes trains, automobiles, spacecraft, and airplanes. And many of the airplanes have been mounted on poles. When you exit the highway to get to the museum you'll notice that it looks like a 747 is about to land on the museum! You can climb up the stairs and go all through the aircraft. And to get down to the ground you can take the slide!
