The Airport Frankfurt-Egelsbach is a German commercial airport near Frankfurt. Due to photo realistic textures of the buildings and vehicles and a 0.5m/pixel ground texture resolution the scenery looks very authentic. With its high-resolution day and night textures, the animated wind display on the tower and several other animations like hangar doors and the fire brigade the airport feels virtually aroused.
