Hello Maria, Bob and All,
 
I see what you mean by a chimney effect providing additional air for the fire. The plane's body could add to the heat if it could reach the ignition point. I wonder what the ignition point is for the metal used in a airliner. I would think that the chimney effect would dissapate heat from the crash point to the upper floors.

I'm certainly no "expert" either, but I would presume that charges placed in the middle of the building would initiate structural collapse from the middle. Nothing says you have to put them at the bottom!  Cheers!

Howdy Tom, I'm no expert but one feature of the towers was rather large
unbaffled elevator shafts.  get a fire going and you have a considerable
chimney effect, also what other materials from the planes and or
structures themselves could have contributed to the flame temperature-
magnesium for example.  once you get a few of the upper floors to fail
there was a pancaking effect as the top floors fell through and added to
the load on the floors below.


wouldn't planted charges caused the structural failure from the bottom
up? That's not what I recall from the videos.
