Everything always falls straight down. That is the direction the force
of gravity acts. What do you think fall means?

Do you have any idea how much trouble demolition experts have to go to
to make buildings "fall in their footprint?" Tall buildings don't
crumple straight down. No one on earth, including all the designers of
the building knew that you could cause an explosion and fire that high
up in the towers and they would collapse, let alone collapse roughly
straight down and take out the rest of the building as it collapses.
