So You telling me that this(A plane's nosecone that was hit by a bird) cut straight through a steel exoskeleton and reinforced concrete...AND came out the other side virtually intact...Yeah OK...😏😏

Doesn't mayer. 767 weighs ~300000 lbs at takeoff.
Meh...good point. But the towers were still designed to withstand impacts like that.
Correct...They were designed with that in mind... The Twin Towers were designed to withstand 150-mph hurricane winds. Dr. Thomas Eagar of MIT likened the impact of the 9/11 airliners on the towers to “a bullet hitting a tree” — negligible.
In a White Paper circulated in 1964, the engineers claimed that the design of the Twin Towers could survive the impact of a 4-engine jetliner at 600 mph at the time of impact.
In 1993 the chief engineer, John Skilling, told the Seattle Times that the towers would not only survive the jet impact, but would survive the fires as well.

Again, what is the first step before a building is demolished?
There are two things that are at odds here. People saying there's no way a plane would penetrated the structure and they were brought down in a controlled demolition
Wire it with explosives?
All structures are significantly weakened.
300k of paper thin aluminum is still paper thin aluminum. Sure the plane has insane energy/force at speeds, but the plane itself cant handle that force and shreds itself absorbing much of the energy in the process. That is why most commercial airliner wrecks look like someone dumped out thousands of bins of trash around a few more solid piece. Don't usually see huge holes in the ground...
No. There are laws to kinetic energy. The material doesn't matter. I have personally seen STRAW (as in actual strands from a pile of hay) embedded THROUGH a 4x4 piece of wood. With enough energy the material will pass through and into another material without deforming until it meets a certain threshold. Same thing here.
The MASS x SPEED is what's important.
The wings were full of fuel, not empty aluminum balloons
The engines each weigh ~6 tonnes or so
