I've been dabbling in planefag, and for the past several days I've noticed surveillance panes flying in circles over Oklahoma City.

Right now there is an E-3G Sentry, an E-6B Mercury, and two Beechcraft 350's over OKC. Over nearby Tulsa there is a Beech T-1A and an aircraft listed as N/A. These planes are doing surveillance, I assume. Why else would they fly around in circles for hours?

I remember reading something about Oklahoma City being the place where the first military tribunals would be held against the traitors...
