Oh well, a loss is a loss and a few Corvettes is no big deal compared to other loses. Like when a fire or tornado wipes out a family's home and all of it's possession's. Now that's a LOSS. A couple of cars can be replaced, or just done without.
Except that most of the Corvettes involved were on loan to the museum from private individuals, so they suffered losses, three of them total losses. Any loss of any type so long as it doesn't involve loss of life is just stuff that can be replaced. That's what we all have insurance for...sentimental value? Some people are probably more sentimental about their car than their house.
The fortunate part of the entire event was that it happened in the wee hours of the morning when everyone was still in bed, and not during the day when there would have been a load of people touring the facility.
