An old army base that was attacked from above in what was supposed to be an air show. Someone had got in and swapped some of the demonstration rounds and bombs with the real thing. That spelt disaster for the viewing public. Now the hangers provise shelter from some of the blood thirst creatures that lurn in the shadows and their ammo is held close by on the off chance of an attack from the Mutants. The runways and war planes are still used, to check out areas that are out of bounds to the rare, uninfected humans.
