In this picture, you can see that the cab frame member is indeed bowed
inward, towards the epicenter of the alleged blast. Again, if
you're talking an explosion, it would not be going towards the blast,
but away from it. Strike three...
This doesn't get into the fact that while it's a fuel-air explosive,
Oxy-Acetylene is a relatively low velocity explosive. It's slower
than ANFO in velocity- meaning that it's less explosive than
ANFO. ANFO is Ammonium Nitrate/Fuel Oil and is typically used for
cratering charges to do things like remove stumps, etc. on a
farm. It requires something to contain and focus the blast so
it's effective. Oxy-Acetylene is no exception to this- most of
the stories you hear about where people get really hurt messing with
these things is when they're
stupid and try to Darwinize
themselves by accumulating a
large quantity of
Oxy-Acetylene (like a garbage bag full of it...) or into a
semi-inelastic or inelastic container like a 2l soda bottle or a can or
gas cylinder. Four regular or large sized baloons might be
enough, but there's not really enough velocity present with the
explosive in question to do much in the way of damage, especially if
the door was open like it was surmised in the story.
Did it happen? I'm inclined to not think so. The story
itself
may be real, but the
truck we've been shown isn't the truck described in the story.
Can't be.
So, if it wasn't an explosion, what happened to this truck?
My WAG on this is that this truck had
something come through the top from the direction shown in the above
picture by the blue arrow. The impact against the back seat and
the buckling in the bed seem to indicate that something solid hit the
truck from the top at the angle shown by the arrow.
