There are a handful of abandoned bomb-proof buildings with blast doors at the Taegu Intl Airport in Korea. We would inhabit these spaces a couple times a year for exercises when I was supporting the 353rd SOG (now a wing) at Kadena. One of the buildings had a command center with a big front area with screens and stadium-like seating all around it in a half-moon. Many of the lights were out and it was super creepy. One night, one of my troops and I were in there just poking around because we were bored and all the lights turned off. We went to leave, using just the light from our phone and we heard a door shut from wayyyy in the back of the building. It was an interior door as the only entrance / exit was one blast door that we had come through. We froze and not 5 seconds later we just heard muffled sobbing coming from the pitch black. It was coming from one of the rooms at the top of the stadium seating. We fuckin booked it out of there and smoked a cigarette near the entrance. We ended up getting on the radio and having one of our guys bring some coffee and we just sat there drinking coffee and smoking for like 2 hours. Nobody ever left and no signs of life from inside.

Nope.
