This video was taken by Charles Gifford, who sought refuge in a storm shelter from the F5 Tornado that ripped through Moore, Oklahoma two days ago.  Secure within the shelter, Gifford was able to point his camera through a small hole, which allowed him to capture an insanely intimate video of the 1.3 mile wide tornado.
One can only image what it must have been like directly under it, and how difficult it is to survive exposure to a tornado's churning debris field. With all kinds of debris flying past, blown by winds reaching 210 mph, you wouldn't stand much of a chance.  Tree branches rip off and fly through the air.  Power lines can be heard snapping and you can see an actual car tire whiz past at around the 0:37 mark .
Fortunately, Gafford survived, but neighborhood was obviously ripped to shreds.
