Today in Omaha, NE there was an industrial accident at a business where one would expect to find combustible dusts. The accident resulted in several employees being treated for burns and there are two confirmed fatalities as of this evening. And although, we were quick to point out this accident may have involved a combustible dust explosion I now believe that the collapse of the structure was the initiating event and any fires and explosions were secondary to the collapse. Bear in mind this is a THEORY based solely on photographic evidence from OUTSIDE the facility; however, these photographs provide very strong evidence to back up my theory. Using my cause and origin investigation skills from way back in the day I can see (and NOT see) the following using the aerial photos provided by the Omaha Herald (http://odc.omaha.com/index.php?u_page=5002&p=5039)
