U.S. Air Force bases & Terrorist Attacks
Many key U.S. Air Force bases and organizations never adequately created or tested plans about how to continue essential operations in case of a terrorist attack or natural disasters from earthquakes to tornadoes. Ref. Source 4
If a terrorist tries to attack a airforce base they are going to have to do some careful planning to be able to get in to the base to attack a certain building. If it is a frontal attack they are not going to get far.
If it is a natural disaster then the air force will clean up and continue as before as repairs are made.
