Except for Shepherd Smith on Fox news. Gosh I dislike him more and more.
A few asking could it be terrorism. That's a valid question. Not likely, but valid.
The Dept. of Homeland Security has just discounted the likelihood of terrorism.

Most likely structural

How do they know? Did they invent star trek level scanners while no one was looking?
IOW - it’s just a little early to rule out any cause.
