Update: I contacted a TV station in Las Vegas -- NBC affiliate KVBC -- and they already have the story. It's not a meteorite, it was a dummy test weapon that landed on a truck at Nellis Air Force base near LV. So, false alarm, as I suspected. So ignore what I wrote below.
An unknown airborne object, rumored to be a small meteorite, has struck a car in North Las Vegas; no injuries reported.
That's all I know. They don't give any sources, any quotes, nothing.
I'll see what I can find here, and update this when I get something.
What would the casinos pay out for this? And why couldn't it wait until TAM 7?
