In June 2008, a tornado hit Kansas State University's campus destroying only one building: their wind erosion lab.

In 2008, the weather was not kind to Kansas. The state was hit with 187 tornadoes that year, more than any other state. Over Memorial Day weekend of the same year, 412 separate tornado and thunderstorm warnings were issued to the state. 

The damage caused, as you may remember from the news, was nothing short of catastrophic. Kansas State University wasn’t exempt from the damage, with several buildings harmed on campus. 

The engineering complex, though still standing, faced significant damage, as did the building that housed the university’s nuclear reactor. Both buildings were still standing, though, despite the 20 million dollars of damage to the campus, which included damaged or torn off roofs and blown out windows. 

Because nobody was harmed, it makes it considerably more comedic that the only building destroyed was the Wind Erosion Lab.
