Interesting that you draw comparisons to nuclear detonations. I
also saw comparisons in the trail left behind, particularly in
the sections where the 'main burst' seems to occur, where the
debris afterglow lasted the longest. It's color reminded me of
the brownish-red haze (ozone and other nitrogen compounds) in
the mushroom cloud of nuclear tests. I understand this is basically
the intense heat 'cooking' the atmosphere into these compounds.
I thought that maybe the same 'cooking' occurred in this event.

Anybody concur? Or am I out of the ball park?
