From what you describe, your experience with explosives extends to bombs designed to have a wide spread of damage and to kill/injure humans. Not explosive devices made to only damage one part of a steel structure.
What do you suppose caused the phenomenon seen in the videos?
You mean the "phenomenon" caused by the surge of air pressure caused by the weight of the collapsing floors?
Those are not squibs nor cutting charges.
You've been sucked in by an A&ETruth crap-ola piece where a guy who doesn't know what he's talking about talks anyway.
The Troofer lack of knowledge of CD is so painful. Try to find a competent demolitions expert and run this by him:
We're going to crash a pair of 767s into the Twin Towers, and we need you to rig it with explosives to ensure they come down...but not at the moment of impact, maybe an hour later so we can get the live TV coverage.
...Oh, and we need you to rig WTC7 to blow, but 8 hours later, and you can use explosives that make noise.
After the guy stops laughing, he'll tell you that two 767s are enough to to the job. That's what engineers KSM, UBL, and Atta saw when they did their math, and they're the only engineers who count when talking about 9-11.
