sorry but the act of collapse does NOT explain the collapse.
So why doesn't lord Gage the first lay out how the towers were brought down?
All I've heard him say is 'it can't be this or It can't be that".

I found out that the steel floor plate decks at that side of that tower at that floor were not laid along, but instead were laid perpendicular to the exterior columns.
Which meant that the trusses under those floor plate decks could never have sagged and pulled those decks down, to be visible in that photo in the NIST report.
You looked at the wrong building. The photo was from the south tower. The trusses were running perpendicular to the pulled in wall on both buildings.

Thermobaric materials can provide significantly higher total energy output than conventional high explosives. The majority of the additional energy is available as low pressure impulse and heat.
An apparatus for simulating, in conjunction with a source of ionizing radiation, intense pulsed electromagnetic fields and time varying air conductivity caused by the gamma radiation associated with a nuclear detonation
The Russians use fuel-air and thermobaric interchangeably, though there may be a technical distinction in the scientific community.
Another combined approach to further improve the metal combustion efficiency is to use a more reactive metal as part of, or as the entire metal fuel component. New reactive metal materials such as nano-sized aluminum to increase the reactivity, titanium and boron alloy to increase the thermal output, and magnesium/aluminum alloy to lower the ignition temperature are among the most promising approaches to increase the metal combustion efficiency. More powerful explosives such as CL-20 that are capable of raising the detonation pressure and temperature are also extremely beneficial.
There exists a need in the art for new explosive formulations with new reactive metal and metal composites to have 50–100% higher blast energy than those by the baseline composition such as Tritonal or PBX N109. Further, the new formulations coupled with new warhead designs will have the potential to form one of the most powerful thermobaric warheads, when compared to the weapon systems that currently exist.
9. A composite explosive comprised of conventional explosive material and a mixture of metals which form an intermetallic compound upon detonation of the conventional explosive material, the mixture of metals comprising boron and at least one other metal selected from the group consisting of lithium, titanium, hafnium, zirconium, tantalum, uranium and mixtures thereof.
Furthermore, the blast from the conventional explosive material propels or spreads the hot and/or molten particles into the environment in the area surrounding the explosion.
In addition, other metals that are reactive with water at elevated temperatures may be added to the reactive mixture, including aluminum, lithium, copper, zinc, magnesium, beryllium, sodium, potassium, calcium, rubidium, yttrium, uranium and cesium.
A reactive mixture comprising 68.88 weight percent titanium powder and 31.12 weight percent boron powder, designated as TB100, was used in each of the following examples. The particle size for these powders was less than 44 microns for titanium and less than 3 microns for boron.
Arsenic, cobalt, cadmium, thorium, and uranium are present in relatively low concentrations in the leachate solutions (maximum concentrations of 3.3, 3.2, 1.6, 0.5, and 0.5 micro-grams per liter, µg/L, respectively). --snip-- barium (62 µg/L)(maximum concentrations listed in parentheses)
Results of the leach tests indicate that the dusts released from the WTC collapse, when exposed to rainwater or wash water, likely produce slightly alkaline to quite alkaline, calcium-sodium-potassium-sulfate-bicarbonate-carbonate solutions.
At least some heavy metals and metalloids may be readily leached from the dusts: aluminum, chromium, antimony, molybdenum, and barium are generally leached in the greatest amounts, but other metals such as zinc, copper, manganese, titanium, vanadium, lead and mercury are also leached in measurable quantities.
