The list is out as far as what airports are being targeted to be closed:

http://www.faa.gov/news/updates/medi..._Be_Closed.pdf

ADM Ardmore Municipal Ardmore OK
LAW Lawton-Fort Sill Regional Lawton OK
OUN University of Oklahoma Westheimer Norman OK
PWA Wiley Post Oklahoma City OK
SWO Stillwater Regional Stillwater OK
WDG Enid Wooding Regional Enid OK

Of lose listed, LAW is the only airport currently receiving scheduled commercial passenger service (American Eagle). Probably the more distressing one on there is going to be OUN. The airport is the 3rd busiest in the state with a significant amount of business and flight school activity.

Story in the Transcript today mentioned that the contract towers typically cost around $600K a year to operate and the FAA staffed towers well over a million a year.
