> My elementary school was originally from the early 20th century and it had the vestiges of the subsequent wars: bomb shelter signs, eerie hallways without windows, heavy metal doors to transition between sections of the building. Some/all of that have less to do with war and more to do with general disaster preparedness. * Bomb shelters provide shelter from...bombs, yeah * Windowless hallways provide shelter from tornadoes (no glass to break/become shrapnel) * The heavy metal doors are firewalls that automatically close when the alarm goes off (most are hollow, won't do shit against assault weapons and predate even Columbine)
