Chemical Explosion in Jacksonville!

http://edition.cnn.com/2007/US/12/19/florida.explosion/index.htmlToday a chemical lab in Jacksonville exploded. Witness say that when the explosion occurred a mushroom shaped cloud of smoke filled the air. I think that the chemical lab was working with the chemicals that go into nukes. So a very big area well be evacuated soon. This, has already begun. Police have evacuated the entire industrial district. It has been confirmed that three workers are missing and two presumed dead. The workers who survived said they heard a hissing noise then a "sound wave". I think it had something to do with a gas-leak and maybe a malfunction. Police say that a gas-leak could have been the problem. Who knows?
