The good fellows of NokNok have access to a wind tunnel for some reason, and so they dropped the Lumia 800 inside to see what would happen. The wind tunnel got pumped up to 3,603 miles per hour, which is just under Mach 5, and supposedly is something like the speed of a jet in a nosedive. The Lumia survived, but it didn't come out without some scratches. That's not too surprising though.
Still, this is something we want to see more.
