Even as a child, you probably never imagined a model plane system as comprehensive as the Miniatur Wunderland railway in Hamburg, Germany.

After 6 years of construction, the "Knuffington Airport" now boasts 200,000 mini people, 6 miles of track, computer-controlled airplanes that actually fly and a $5 million bill.

Since its debut, it's become one of Germany's most-visited attractions. Visitors who stop by can watch everything in action. From train, car and emergency vehicle activity to planes taking off and landing to the occasional "disaster" that must be tended, this model airport leaves nothing out.
