ouch!

Um, when did old GT mountain bikes come with carbon steerer tubes?

Most importantly...

*the bottom 3 spokes on the front wheel are visibly BENT*

I guess this answers our spokes hanging vs. standing debate.

That's what I love about carbon steer tubes, but why did his chain
fall off at the same time?

That's not a carbon steerer tube. It's a threaded headset.

His chain didn't fall off. If you bothered to look at the picture
with more than a cursory glance, you'll notice that the chain is
still wrapped around the small chainring. As Paul H mentioned, it's
post-jump, as is the following photo I recently took with the same
phenomenon present.

That's hardly the same thing. To me, it looks like the problem is at
the rear cluster- follow the line of the chain towards the rear. That
ain't normal.

There are many interesting things in this photo, which unfortunately is
too low resolution to make out the details. For example:

-what is the black line going from his back knee forward?
-what are the two black lines crossing his front tire, between the
stem and his lower hand?
-what is that thing that looks like a straddle cable and yoke in the
same region?

It's not clear at all that that is a threaded stem. The resolution just
isn't good enough, but for example, there appears to be a stack of
spacers at the bottom. I know of no threaded headset that looks
anything like that.

Then I take it you haven't seen too many dirt jump photos. The chain
inertia can easily pull the derailleur completely linear.

There are many interesting things in this photo, which unfortunately
is too low resolution to make out the details. For example:

-what is the black line going from his back knee forward?

Rear brake cable

-what are the two black lines crossing his front tire, between the
stem and his lower hand?

Rear brake cable/housing and rear shifter cable/housing

-what is that thing that looks like a straddle cable and yoke in the
same region?

A straddle cable and yoke, most likely.

It's not clear at all that that is a threaded stem. The resolution
just isn't good enough, but for example, there appears to be a stack
of spacers at the bottom. I know of no threaded headset that looks
anything like that.

It looks like the locknut and cup. The diameter of the vertical portion of
the stem is such that it would not be large enough to clamp around the
steerer. I think it's threaded.

Possible scenario:
Chain breaks.
Rider falls forward onto bars.
Steering column snaps.
