Eight vintage Corvettes — one of them the only one in existence — plunged into a giant forty-foot sinkhole Wednesday morning at the National Corvette Museum after the floor collapsed.

The accident occurred sometime around 5:30 a.m. Wednesday morning at the Corvette museum in Bowling Green, Kentucky. The hole began to form around 5:30 a.m., according to museum officials; power was lost at 5:39 and police were called to the scene.

When they arrived, personnel discovered a 40-foot sink hole between 25 and 30 feet deep.

“It’s pretty significant,” executive director Wendell Strode told the local Courier-Journal.

Staff removed one car, a 1983 Corvette, but others will remain in the ground until the structure surrounding the hole has been assessed.

The Courier-Journal reports sinkholes are frequent in Kentucky, where the museum is located.

“Bowling Green — about 60 miles northeast of Nashville, Tenn., and 100 miles southwest of Louisville, Ky. — is at the edge of a karst region where caves, springs and sinkholes are common,” the paper’s Mark Boxley wrote. “The main entrance to Mammoth Cave National Park is about 30 miles northeast of the city, but that cave system has more than 400 miles that have been explored.”
