Reply #148: I don't understand the point you are trying to make.

Please clarify.

If you understood my demonstration, you would understand I have shown that the 9-11 report cannot be true. Are you now saying I'm wrong because the building actually fell in under 10 seconds?

Please clarify. I'm trying to understand what it is you need.... not that it's my job to serve your needs.

Actually, if you tell me the time you'd like, I can add in a fudge factor and produce that exact time for you. Is that what you want?

Above, I have shown the absolute minimum time it would take to bring the entire building down. Now, do you suppose that time would get bigger or get smaller if you added air resistance?

Note, in the many pictures we've seen, there isn't much of a building above the demolition wavefront. So, there if very little mass to transfer momentum. In addition, with less weight% of design load that the lower floors must carry, they'll require even more force to pulverize them. Gravity can't help the collapse if there's no building above it.
