Did we learn anything?

NOOOOOOOOOOOOOOOOOOOOOOOOOOO

It was all the planes!

No amount of physics could have stopped the 100+ floor towers from collapsing. The impact of the hijacked planes and the outcomes from the collision were too much for any perfectly engineered (from this generation) to withstand.

All we can hope is that in the future we can use this horrible event to our advantage to help figure out ways to prevent this kind of catastrophe.
