Mythbusters did some experimentation in a pressurized arirliner cabin. They shot holes in the fuselage, they shot holes in the windows and even blew windows out without any structural damage to the plane. It wasn't until they used actual explosives that they did real damage.
Mythbusters rocks!
I saw the one last night about the myth of jumping up into an ordinary ceiling fan & getting decapitated...BUSTED!!!
However, the homemade lawnmower fan was cool....!
