OK, the notice on the website http://www.airmanflightschool.com is plain black text on a white background, stating that the school is closed until further notice, with a hit counter at 2028 as of my visit.

It has been combined with OU flight school -- article in the Norman Transcript today. You have to check out the link and be sure to look at the picture for the article -- enlarge it.
