My guess is that they had a loose or broken fuel line,
caught fire and the fuel vapor exploded and the fire melted
the spar enough for it to fail.

Boy, I sure hope that's "all" it was. (Who'd ever think we'd be saying that
kind of stuff?)

With everyone describing an "explosion" (which the video tends to
support) -- and Chalk's not having to do much in the way of security
screening, as a small carrier -- this could easily have been some kind of a
nut-job with a shoe bomb and a "cause".

And *then* we'd start seeing all sorts of stupid proposals for "enhanced
security" that we don't want or need.

Sad to say, a mechanical problem is the best-case scenario.
