Lakeland was a bit different because it was part of a nationwide tower cutback. Oshkosh wasn't on that list, as far as I know. So why single out one airport? The answer, I think is the administration wants to target GA and the jet set. That's why this so important.
EAA should strongly push the grass roots image now!

Did the FAA promise to shut down the tower if payment was refused? What is the FAA plan if payment is refused?
