I'm getting some major Close Encounters of the Third Kind vibes.

but in all seriousness, my prayers go out to all the families involved.
I'm sure eventually (if it's not out there already) some random blog site will post some crazy theory that the plane hit a UFO or something.
Anyway, terrible (especially for the families) that they have to wait another 10 hours or so every night to keep searching, etc. I know the chances of anyone surviving at this point are slim to none, but if by some miracle someone is alive, those 10 hours are huge.
