OSH Class D airspace
 

Does the airspace around OSH remain class D during Airventure?

You bet and then some..... Special "OSHkosh Rules" go into effect several days before the event and remain in effect until it is over. A Special NOTAM containing the "Rules" is available at airventure.org and should be online by now, all 30 or so pages of it. Don't leave home without it!

Also, remember the airport is closed over night and during all airshows.
