What kind of explosion starts like this? It does not propagate from a source point and go outward, it is like an invisible gas cloud was suddenly ignited but keeps glowing for such a long time. I have never seen anything like it.

(vid related) is zoomed and slowed down to emphasize

Speculation:

Was the underground structure filled with a highly explosive gas and then ignited?

Was the RV parked where a hole could be drilled and gas pumped down? (manhole covers in the street in that area seem to be positioned only in driveways where parking would not be allowed).

The detonation characteristics of the GBU-27 does not match any of the videos from nashville AFAIAC.

What's your take on that?

uh? elaborate please.

And that means it will change totally in it's detonation characteristics from this (watch vid):

into this (watch vid):

??? I want to understand your line of thought.

I don't buy that. None of the videos shows a moving fireball, only a suddenly appearing one that stays in place for a moment while it increases in intensity until it diminishes and the smoke appears.

In your theory, there would be a fireball that shot out of the ground/building with momentum. Vids show no such thing. Even the street vid seems to show an invisible gas cloud igniting (white-out) before "source" light up brighter.
