 The show starts Monday, but there's already 4,000 aircraft at the airport. This year, they're highlighting the 100th anniversary of the Canadian Air Force, and with that comes the Canadian Snowbirds along with the Canadian F-18 Demo Team. But don't worry, it won't all be about Canada this year, as the Wisconsin Air National Guard will be flying, along with U.S. Navy Growlers and Air Force F-22 Demo Team and a lot more.
