A large explosion at a Kansas grain elevator yesterday killed at least three people, injured two others, and has at least three more missing, reports the AP. Officials say the explosion occurred around 7pm in the northeast Kansas town of Atchison, sending a massive fireball so high into the sky that it was seen in neighboring Missouri and shook buildings up to four miles away. The injured were rushed to a severe burn unit at a hospital 50 miles away. "All I saw was a flash and then the building shook really good," said an employee from a store located two miles from the blast. "Some things fell off our shelves." (More explosion stories.)
