why not fly the planes out of harms way? Why leave them at the airport? I used to keep my boat at a very good Marina, since it was only 24' and I have a trailer, I was told that in the event of a huricane I was suppost to get it to a safe place. Not to leave in at the Marina, seemed reasonable to me. I am surprised an air port doesn't have a similar policy.
I'm sure now they wish they had. Looks like some were tied down with 90 mph rope or in hangers.
