A 40-foot sink hole at the National Corvette Museum in Bowling Green swallowed eight of the sports cars on display inside the the facility’s iconic Sky Dome Wednesday morning. Some time before 5:30 a.m. the sink hole started to form, authorities believe and by 5:39 a.m. power in the museum was lost and police were called.

When they got to the museum, emergency personnel discovered a 40-foot sink hole between 25 and 30 feet deep. Six of the damaged cars were owned by the museum and two — a 1993 ZR-1 Spyder and a 2009 ZR1 Blue Devil — were on loan from General Motors.

The museum is about a mile from the General Motors Bowling Green Assembly Plant where the car is built. The other cars damaged were a 1962 black Corvette, a 1984 PPG Pace Car, a 1992 White 1 Millionth Corvette, a 1993 Ruby Red 40th Anniversary Corvette, a 2001 Mallett Hammer Z06 Corvette and a 2009 white 1.5 Millionth Corvette.

Emergency personnel allowed museum staff to remove one car, an irreplaceable 1983 Corvette which was not in the sink hole. A monetary estimate of damage done to the museum and the vehicles involved had not been determined early Wednesday.

If you're a car guy, this truly breaks your heart.
