Springfield, IL too.

I haven't been everywhere.

At least a 1/4 century ago, during the Cold War, the FAA
began to build new, secure buildings for all their offices
and towers, moving them into buildings the feds controlled,
rather than being in terminal buildings controlled by local
airport boards. All these new buildings have the same sort
of security in the landscaping, access and structure.



See Denver. The controllers have to go thru the same TSA screening that
passengers do to get to work.
