I really have nothing to say about this - I just think it's unreal and deserves to be shared far and wide.
It's like The Greater Cosmos(tm) saying: "Just when you thought the NFL season couldn't get any weirder - here's a stadium roof collapsing! And make sure you catch it on camera!"
(Just for the record - it was nice and sunny out here in Utah. I didn't even need my coat today. Neener, neener).
The weirdest thing is last night I had a dream I was on the Titanic while it was sinking (it's a dream - just go with me, here) and it was making that same noise (I also remember floating underwater and thinking that James Cameron's CGI work was a bunch of crap. Oh, how I love my subconscious).
