I doubt anybody survived that crash. What a shame for the victims, their families, and the museums.
I live close to the largest flying museum known as Planes of Fame in Chino CA (www.planesoffame.org)
They put on a huge show annually. These shows are not without risk. Prayers for all involved.
I didn't even know they were having that show at that airport. I haven't been there in quite some time and I'm sure much has changed. My office was there way back when I was commander of the police helicopter section which, as far as I know, is still based there.
