Have you ever wondered why the departure procedures from Oshkosh and its surrounding airports are so brief compared to the complex arrival procedures that govern airplanes heading into the show. It’s an easy explanation.

Air traffic control is concerned primarily with airplanes not running into each other. At Oshkosh, they’re not even particularly concerned about them not getting too close–the air show has reduced separation standards or else all those airplanes would never be able to make it in.
