Is this type of bomb even feasible for this CT ? I was under the impression that thermobaric bomb types were very large and unwieldy things, from 500-1000 lbs to the giganto- BLU-82B "Daisy Cutter" that uses a similar mechanism and is ~15000 lbs.

In a large, complex building with multiple materials and fire pathways (a firefighter could probably produce a better term), the patterns of how a fire spreads will be logically be more complex. Reconstructing those "pathways" and patterns becomes even more difficult when the large building then collapses.

I sincerely hope there was nothing about these last few posts that violated any forum rules...
