If any of the posters here had other sources for that person's death, I'd be concerned.
The second name I saw mentioned on the other site was someone's unsourced info that a political VIP had been in Reno (no mention of attendance at the Air Show). He's not my cup of tea (not intended as a pun), but is certainly a major figure who has fans here.
Harry Reid's statement did not sound like either one of these people (both definitely known to him) had been injured or died.
I'll say a prayer for all concerned and go to bed without worries about these two.
The other poster's source makes me just a touch nervous, but I'm still pretty convinced it's almost certainly not true, as it would be almost certain to be public by now if it were true.
