The TSA has proclaimed a 50nm Temporary Flight
Restriction (TFR) centered over Wittman Field at Oshkosh (WI), for
the last two weeks of July, and the first week of August. No aerial
activities whatsoever will be permitted in that area, below FL
400.
The rationale was explained by Richard Johnson, the TSA's top communicator: "We saw a crucial need to protect all those people and all those aircraft, from all those people and all those aircraft, so we invoked our unbridled powers to protect all those people and all those aircraft on the ground."
When we pointed out that "all those people, and all those aircraft" wouldn't be there in the first place, if there were no flying, he replied simply, "See?"
