When you attend the event, you can pre-purchase a DVD containing highlights they assemble after the event.. this *looks* like one of those, but I could be wrong.

Here is the website for their public videos:

Also, you can control webcams within the museum itself here:

I must say, having the biggest aviation event in the world in my backyard is freakin awesome to someone who loves aircraft like myself. Even if I don't attend the event, we usually see inbound aircraft here in Milwaukee. Saw the airbus land on it's way up. Looked like a big FAT MONSTER bird. The whole time I was thinking of like the cartoons where a character will be flying through the air and then another says something like "Hey! You can't fly" and then they just fall. Not that would ever wish an aircraft to just fall out of the sky, it's just surreal seeing it in the air and my brain is saying "Hey! Thats way too big to fly!"

It really is a fantastic airshow and only a hour away from me. There is always so much to see.
