Scroll down a bit for the NWO mention on the time capsule capstone. That is in the "great hall" (outside of security). I forget where in that area though.

Most (all?) of the conspiracy signs put up during the Great Hall construction are gone. I didn't notice any the last trip.

Upstairs in the middle of Terminal B is a Voodoo Doughnuts. They have an alien picture (holding a donut).
