So What Happened At American in Tulsa, with the car damage onsite?
 

The news reports are very vague but it sounds like someone onsite was shooting at the cars in the fencing with some industrial pellet shooting tool? What kind of industrial tool shoots pellets?

Don't know, I'm just glad I was across the country last week!!

I talked to my neighbor who works out there. Apparently a big industrial shot peening machine is the suspected device. Supposedly when the shot pieces are worn and small enough to fall into the hopper holes they are supposed to drop into a bin. And some are claiming that the machine blew up and shot the shot pieces into the parking lot. The suspicious thing is that one car may have lots of damage when the car next to it has none. Very suspicious.

Where were the cars parked that got damaged? Up close to the buildings, or farther out?

He gauged the distance about 30-35 yards.
