I didn't want to hijack Seabreeze's thread on model railroads, but I knew this video of a working airport runway system existed and it came to mind when I watched the railroad video. If you like working models, you will be fascinated with the creativity of the German airport working model in this video. I love watching the takeoffs, especially the Lufthansa Boeing 747 and the UPS DC-10. It takes a lot of creativity along with some engineering skills to create something like this.
