Think of how many airports around the US have subway systems, and rather extensive at that. I think it pretty unlikely that this area would hold any kind of key to the important tunnels of the regime.

True .. but our Airports tend to do a bit more business then airports in Iraq

Fox says one tunnel goes all the way to the river. I thought they said quite a few miles.

Indianapolis Airport does not have any major tunnels, as far as I know. But then, we don't have subways here, either. In Indianapolis, you leave the terminal and walk across the street to a parking garage. That's it.
