the 1968 WTC had a state of the art exoskeleton design, modern fireproof coatings, modern fire suppression systems and I'm sure a few other design advantages over the 1930 empire state building.
Those weren't advantages. The construction of the Empire State Building is solid. The construction of the Twin Towers was like tissue paper by comparison. When the planes hit the towers, the massive engines drove through the outer walls, and the fire was injected into the heart of the buildings. It actually came out the other sides of the buildings. This blew off the flimsy, sprayed-on fire resistant coatings that covered the support steel, allowing the fire to get directly to the steel. The steel was softened by the head, and collapsed, creating a pancake effect.
What really brought down all three towers of the World Trade Center was their design, which was similar. It did not work against fire. It was a faulty design.
All of that, and the construction itself was a very modern suspended floor design that allowed for maximum windows. That is, the floors were suspended around the central column from the corners with no rigid structure in the way old-school girder and panel building were constructed. Break a couple of those floors by mechanical stress and they all start coming down around the center column.
This picture, taken in 1972, illustrates this. The buildings had no interior walls when constructed, so you can literally see right through them. https://pic8.co/sh/z0i5OE.jpg
This is correct. This is why when people say, "but muh steel building", is dumb. Each design brings significant differences. This specific issue is why fire retardant spray is a REQUIREMENT for structural integrity of the building in fires. Additionally it's rating only lasts for specific durations at specific temps. The fires well exceeded the safety margins. Never mind it was over due for replacement and well documented as fraudulently installed (never up to code) in the first place. Additionally, much had come away from the structure, which is why they were due for a complete re-installation. Which was a requirement for their continued insurance coverage.

The construction of the Twin Towers was like tissue paper by comparison.
Steel Exoskeleton design vs aluminum airplane. The exoskeleton sliced those planes like an egg slicer at 250MPH. Each floor was fully supported by the exoskeleton, there were no interior load bearing walls. The planes hit, were sliced and diced by the exoskeleton, blew through the windows, through the whole floor with minimal resistance (cubicles, no heavy load bearing walls, elevator shaft, power/water/communications room) and to some extent emerged out the windows on the other side. I would not call this design tissue paper.
This blew off the flimsy, sprayed-on fire resistant coatings that covered the support steel, allowing the fire to get directly to the steel. The steel was softened by the head, and collapsed, creating a pancake effect.
That IS the official narrative they want everyone to believe so no one bothers to research it more deeply.
Explain Tower 7? No impact, no fire, collapsed in it's own footprint along with the others. Why?
