This video is fantastic, but why set it to the soundtrack from Kundun?
Knock it off guys, anyone could recognize this is "VI of IV" by Pauline Oliveros.

Wonder if his insurance will cover sinkhole damage?
They have a press conference on their youtube channel where one of the museum reps mentions they have sinkhole insurance, which is probably common if not required in that part of the country.

Looking at the aerial photos of the facility, they're right next to a storm water drainage pond. Maybe that was the source of the erosion?
Everything in that area is limestone with voids, that cave has probably been under there for thousands of years. I had to do some quarry drill demos at a pit just down the road from here and there was a big void right under our bench too, makes things a pain in the butt because you have to be sure you don't load explosives into any hole that intersects a void or you will end up putting waaay to much in and then your neighbors will be upset when very large rocks get mortared into their yard/roof. I think I posed this on poenews way back when, but I did some video with the quarry cave when I was getting bored waiting for the mechanic to show up:
And yeah Mammoth Cave is just up the road too. Just the nature of the area, they probably should have done a more thorough survey before they built the museum.
an aside, who do I contact to get RockBolt fired?
Because while I'm not at all familiar with demolition, I am pretty damn sure if you're filling a hole with explosives and it doesn't fill up after an expected amount is added, the solution isn't to just keep pouring in explosives until it does fill up.
You'd think blasters would pay attention to that but its not always the case. Unless you are in a very wet area you tend to use bulk anfo loaded from a truck boom (they are little spheres like sprinkles). Granted only terribly inattentive blasters might keep the button pressed far too long before they realize the hole isn't filling up (but it has happened!), but even if you do realize it and stop, a hole's worth of powder is now somewhere else. Is it at the bottom? Was the void in the middle? Unless your driller was really paying attention to the way the drill was behaving and taking notes you probably don't know. So pretty easily you can end up with a really lopsided powder distribution, and at best you're going to have too much oversize and undersize rock and at worst something is going to land somewhere inconvenient:
Anyhoo, I just work on the technical side with the drills, and most of the places I go blasting is done by an outside contractor so I just get to sit and watch when things go bad.
At least the 1962 and the 2009 "Blue Devil" ZR-1 look relatively unscathed, though I'm guessing the fall gave their leaf spring suspensions quite a workout.
I'm guessing the PPG pace car, which was the first one to fall according to the security camera video and which is probably under the visible cars and a big chunk of floor, would be a total write-off, which is a shame, it was a magnificent car in a beautiful shade of orange.
One idea on NPR that was suggested somewhat in jest but sounded kind of cool was if they couldn't pull the cars out without destroying them, filling the hole in with epoxy or putting a thick plexiglass window down as a new floor would let tourists look down and witness the Lost Corvette Crypt.

I feel like whacking that thing with an orange crowbar.

Why the crap did they leave the audio in?

So many Hotwheels in that hole.
