The tour will start in front of an abandoned aeroplane Douglas C-47 Skytrain or Dakota. This wonderful piece of aviation history welcomes curious visitors open-winged. We will use this rare opportunity to climb ON the aeroplane and explore inside. We'll then proceed to the runways. As we drive cautiously on the endless runways, we'll try to imitate and imagine what it felt like for pilots to take off. Driving across runways, we begin to catch views of a plane-shaped hole in the hill. Reaching the entrance of the tunnels, we are in front of the highlight of the tour. While checking the torches, we will get to know the basic information about the object and the safety rules that we need to follow. During our 3-kilometer walk through dark tunnels, we will talk about construction, operational days and destruction of the base. We will cover personal stories and experiences of employees, relationships, and conflicts. The tour will end back at the aeroplane.
