Sinkhole opens up at National Corvette Museum, swallows cars

Watched a video on You Tube of them flying a r/c helicopter with a camera over and into the hole. Amazing. It looks like only 3-4 of the cars are salvageable. The rest are buried or crushed by the concrete. Also looks like is not finished, as there are deeper holes just under the base of the red pillar that sticks up to the roof. Also, just outside of the building is a water retention pond.
