There was of course the concrete core for the elevators and uss ducts, etc but the structural steel formed the outside perimeter of the building, 200 yards by 200 yards and the floors of poured concrete were supported(’’carried off’’) by trusses.
That was why the buildings failed. A truss can only support high heat for so long and then it fails.
That and the fact that most of the fire proofing that had been put on during the construction phase had not only falling off at impact but it had deteriorated over the yeas..
Because it is a relatively easier case to make for the conspirators make given it was obvious what brought down the towers.
Of course the Libyans are Moslems. But they were in the film as a joke to provide Doc Brown a way to get plutonium. It might be another joke that Tetroxide can be used to make terrorist's explosives. I know that has got me laughing. ;^)
Where id the towers go? By Judy Wood B.S., M.S., Ph. D.
It is a very detailed heavily illustrated book in hardcover, unfortunately out of reach for most of the general public due to the price which currently is around $ 51.00 at Amazon. It leads us to fires in CA and Maui. Read the book. Visit her website and compare photos to Maui. Brush fire or something else? Same white dust that should be black. Boats with fiberglass hulls untouched while everything else is gone. People burning in water. Cars with melted hoods and windshields but plastic dash still in tact parked next to a palm tree with fronds still waving. Any good Catholics who burns palm fronds knows...they go up like match sticks.. Aluminum wheels melted and flowing across roads next to the ocean. If you can’t see what is wrong, you can certainly feel it. If 911 was about starting a war in the Middle East, Maui is Pearl Harbor for humanity.
Fortunately I was in a position to purchase this book and I am glad I did and it was worth it.
I understand reluctance to see what to some is obvious about wtc7. Ok fine, say heat brought all three buildings down.
Answer me this: the planes hit the towers and exploded in huge balls of fire, intense heat followed. How did Mohamed Attah’s passport fly out of the plane and flutter to the ground, not even burned? How did it end up near the top of the rubble? Why wasn’t the person who “found” it investigated? Was it coincidence that the person who found the passport was next to an FBI agent to hand it to?
Perhaps some day the truth may come out, by then it may be too late.

How would water put out fires on those tall towers?
The elevators were Minoru Yamasaki's trademark "Skylobby" elevator system that didn't use the traditional full-height shafts in a reinforced central core in the building. The center cores were steel columns, not concrete.
"The core of each tower was a rectangular area and contained steel columns running from the bedrock to the top of the tower. The large, column-free space between the perimeter and core was bridged by prefabricated floor trusses."
Construction showing a central core of steel columns but no concrete:
The floor trusses:
Inspectors in the last decade uncovered issues with the steel used in the Bay Bridge in San Francisco and everyone stands around wondering how that could happen.

BTUs are a measure of heat not temperature.
The architects anticipated a small plane strike on the building in their design, but they did not anticipate a 747 striking the building with a full load of fuel.
When the nose of the plane hits, the cockpit windshield blows out and the instantaneous pressure wave blows everything out of the cockpit including the cockpit contents and passport. As the plane continues to smash into the building the internal pressure blowing out of the body of the plane and and subsequent explosion inside the building push the passport further clear of the building. The passport then flutters down or is blown by the wind clear of the building. Remember that the WTC was falling in towards its core rather than outwards. I cannot answer why it ended up on the top of the pile but I can get it out of the plane without being burned. (Wasn't there an attached rooftop 4 or 5 stories up on the side of the building? Could it have landed there?)
Thanks for the correction. I worked in the construction industry in NYC in the late 70’s and 80’s.
My dad was a builder. He knew those towers were in trouble the moment they were hit.
A truss isn’t the same as a steel beam.
ALL commercial buildings have sprinkler systems. I am typing this in a multi story commercial office building(not 100 stories). There is a sprinkler head on the ceiling about ten feet in every direction.
In addition, all tall apartment buildings have water storage tanks typically on the roof or upper most floors to provide domestic water for its occupants. There are companies in NYC that just rebuild old Cedar Wooden water tanks.
Buildings like the Twin Towers would have large water pipes that would be the same diameter used to supply a small town.
I assume they also had tanks on upper floors so that water can be supplied by GRAVITY feed. Keep in mind there were literally 4+ thousand people in each building. That is more people than the town I live in New Hampshire.
IIRC, they used asbestos to insulate the steel used in the construction for the lower floors. They subsequently decided not to use asbestos for the higher floors because of the cancer risk. However, some here stated this type of asbestos was not carcinogenic. Also supposedly, if asbestos had been used, the steel wouldn’t have weakened as much and the buildings might have remained standing.
