"The Secret Underground Airport" is a popular subject in folk mythmaking. However, underground protective structures equipped with conventional Soviet airfields are everywhere. The photo shows the former military airfield Vishchevo (near Vyborg), infamous for the botched hijacking of a Soviet plane by a family of great musicians. Arched hangars covered with earth to protect aircraft, plus simple underground shelters for crews, built of concrete rings. Everything is long abandoned, and airsoft players periodically play in the local buried command post. N. on. We remind you that next week there will be a premiere of a lecture by historian Vitaly Redkin on equipment protection structures and mysterious "underground airfields" at the museum shelter "Underground Moscow".
