After more than six years of construction, the world’s smallest airport was opened in May, 2011. The aerodrome is not only an attraction for aviation enthusiasts, but also for technology fans, for aircraft spotter and for model constructors. Approximately 40 different aircrafts and planes, like Cessna, Boeing and Airbus, are taxing independently on the airport apron. The planes also being moved back from the terminals, taxing behind a follow me car or enter the runway. Furthermore, airplanes are accelerating for taking off, and they are landing on the main runway. Each plane is equipped with original lights and sounds.
