I am an engineer

And if you look at 17 seconds in, you can see that the entire building moves at once.

No single point of failure. At about 15 seconds, some windows blow out.

If a building moves all together, with no single point of failure or weakness, then there is no structure to it. ... (The structure must have been destroyed at 15 seconds).

This is not theory. There is always a single point of failure in an engineering design or structure. Never a complete structural failure in every part of the building at the very same second.

The only adequate explanation, is that there were simultaneous and multiple points of failure evenly throughout the building. How can fire cause this?
