Abandoned factory bomb shelter with planes

An old abandoned and long forgotten bomb shelter. It is located on the outskirts of the city, next to a large aircraft factory. Plundered long ago. What can be seen in the photos below is no longer there, everything has been scrapped. Photos of 2017 from the archive.

In general, it was very amazing to see these planes in the underground shelter. There is an assumption that these premises were used by some private individuals, and there was something like a repair workshop. Since even according to the documents, the shelter belongs to the Aviakor plant, but it is located outside the factory territory. Why all this turned out to be abandoned is unknown
