Sorry to three-peat.
An article came up in my morning feed about wildfire smoke in Wisconsin impacting EAA AirVenture at Oshkosh. Wed & Thu visibility was a mile or less and only IFR arrivals were possible. For which there are very few slot reservations and all are long since taken.
The NWS expectation on Thu was that by Fri when the real mass arrivals start the vis will permit their normal high density VFR / VMC procedures. Here’s hoping they don’t get a midair from the poor visibility.
The organizers are worried about air safety of course. But they’re also worried that lots of ground-based attendees will stay away, not wanting breath smelly and unhealthy brown air for a whole long weekend.
