Iowa A grain bin collapsed and sent a tidal wave of corn into a home, sweeping it off its foundation, trapping a family of four and shaking the ground for miles.
One man was taken to a hospital after being buried for hours in grain and debris in Hillsboro in southeast Iowa.
The bin - about 100 feet in diameter, 90 feet high and containing more than 500,000 bushels of corn - collapsed Monday evening. The force of the grain broke the walls of Jesse and Jennifer Kellett's home and sent the roof crashing down.
"The force actually took the house with the corn and shoved it and crushed it," Dan Wesely, Henry County chief sheriff's deputy, said Tuesday.
The Kelletts and their children, Jordan Walter, 11, and Sheyanne Walter, 9, were trapped. Jennifer Kellett and her daughter crawled out, but her husband and son - pinned by walls, wood and corn - had to be rescued.
Many residents of the town of 200 said they could hear the bin's rivets giving way, sounding like machine-gun fire. Farmers miles away reported feeling the ground shake. The bin was about 20 feet away from the house, authorities said.
