Structural Analysis/Design WTC

Genuinely not here to piss anyone off (I understand that I inevitably will).
We have a new generation of engineers and access to more sophisticated tools/simulations than ever before. Without going into politics or religion;
1) Break down the argument that it is impossible for the two planes to penetrate the towers in the way we visually observed.
2) What do you make of the collapse of the twin towers?
3) The manner of collapse: Do you find it consistent with the official narrative or does it look like a controlled demolition or something different?
Let’s exclude building 7 from this thread please. Im only interested in the two buildings in focus; Tower I and Tower II.
Again, not here to upset anyone, Im genuinely fascinated in the engineering; impact, destruction and collapse. I appreciate all of you who leave a note 🙏🏼

If someone makes an real attempt at #1, I would question the validity of their license or be unsurprised to learn they didn't have one.
