A really big tornado caused extensive damage and tragic loss of life (51 people found so far, of which 20 are children from an elementary school) in the Oklahoma City area on Monday. The tornado was more than a mile wide, with winds of 180 mph or more. It flattened everything in its wake, ripped the bark from trees with its debris and swept cars and like trucks up like Matchbox toys. There is footage of the funnel cloud and the damage on the website of the public news service PBS at this link http://www.pbs.org/newshour/bb/weather/jan-june13/tornado_05-20.html
