RE: where to getwhat you want
Since you guys are talking about plastic sheeting and laminates, I thought about a conversation I had recently with a 3M sales rep. 3M currently makes a plastic film for hurricane protection that you put on top of glass windows that makes them shatter proof. They have a sales video that shows a 2"x4" being shot out of an air cannon that bounces off of a window. The window cracks but stays in place and the wood bounces off of it. This is a much cheaper alternative to expensive, think hurricane proof windows.
Anyway I ran into a 3M sales rep in an airport and he told me they were coming out with a bullet proof version of a similar laminate.
We could cover airplanes with this stuff and in the event of a crash no pieces to pick up! Airplane still intact just a little limp. He told me how to find it on the 3M web site but I forgot now and have never looked. It would probably be a lot stronger that the films we use today. This stuff would probably make a very tough airplane though.
