Supposedly the building was deliberatly designed to take the impact of a 707
impact, it was part of the design specifications, and as such, they had
steel girders every 3 feet, as opposed to every 6-10 feet. What caused the
structure to fail was that the jets that hit it were all long haul jets that
had not gone very far, causing them to have full fuel loads, the heat caused
by the fuel fires reached 1500c (or so I have heard), causing the girders to
weaken, and then the thing went. All things considered, we are luck those
buildings held up that long.

It also looks like a Towerbuilding that came down in
the UK back in
the sixties. It was supported only by the walls of the structure and
a gas explosion took away a few walls. Subsequently part of the building
came down because of the weight of the collapsing concrete above
the explosion. many people lost their lives and building regulations
in the UK were tightened later on.
