I just read about that. At the time of the article they had no idea how many people were on the planes, or if anyone on the ground was caught in the crash.
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.
