Only thing I've heard of like that was from a friend on a flight that hit turbulence with no warning. One of the stewardesses was walking down the aisle and bounced straight off the ceiling and cracked her neck -- dead instantly. Guy said it was like being in an elevator and watching a floor rush past -- the plane dropped and it was as if she stayed in the same place. Everything in the cabin that wasn't secured was smashed.
I was amazed because I figured everything within the local reference frame would just move together. Apparently that isn't how physics works.
