TIME DELAY FROM BASEMENT EXPLOSIONS TO AIRCRAFT IMPACT
The authors have located evidence that possibly shows how long the time was between the initial explosion and the later impact of AA Flt 11 at WTC1.
Jenny Carr was at a business meeting with others on the morning of 9/11 at 1 Liberty Plaza, and a recording was being made of that meeting.
During this recording a first explosion is heard, and then a second one about 9 seconds later. This data still needs to be corroborated, and both authors and the Scholars for 9/11 Truth are involved in this; however, it is worth presenting at this time. This was found inside a movie compendium, "9/11
Controlled Demolitions of September 11, 2001". To repeat, this needs further corroboration.

Isn't the real absurdity of NIST's answer to number one the fact that they are reducing all of the building's resistance to collapse down to the strength of the connections holding the floors to the columns. To me it seems that with only a couple leading sentences and a few "outside the core" phrases they seem to make 98% of the building disappear. (Only the lower part that is... we still need the huge bulking mass on top to do all the dirty work.)

You would actually have to cut a solid chunk completely out and let the column fall down onto itself to produce the kind of shock loading you're looking for, as far as I can see.
Does that make any sense?
NIST tries to prove that a column failure at the 5th or 7th floor initiated that collapse. Thus the whole building, according to NIST, is crashing down only a few floors, then collapses totally caused by the too strong force of this acceleration and subsequent deceleration of its total mass.
What you in fact proposed there, is an "evaporation" of steel components, so a part of the building suddenly wasn't there anymore.
That's what all of us are used to call an explosion, which removes parts of a structure, so it can free fall in itself, started by a sudden global drop which impacts the ground with such great force, that the above still intact structure will be shattered to pieces by the sudden fall-acceleration and then deceleration of its total mass, which will then rain down in broken-up pieces to the ground. A men-made demolition collapse.

And the reports of flooding of the basements.
Water muffles explosions enormously.
But explosions under water in a basement amplify seismic effects also enormously, since the water is 100% coupled to the soil and rock.
