Perhaps to learn clues to prevent a complete, freefall "fire induced"
collapse from happening again, especially since:

It never happened before, but on 9/11 it happened three times. An
executive in the WTC Management said in his opinion the Towers could
withstand multiple 707 impacts, and compared it to a pencil puncturing a
screen netting. Firefighters made it up to the impact area of the South
Tower and suggested nothing major.

And -- White Star proclaimed the Titanic to be "unsinkable", too.


Not to mention WTC management were business types not engineers and
thus were not in a position to provide an educated opinion such as that.

I know WTC was designed to withstand a fully fueled and loaded 707
strike, but multiples? I dunno, I doubt it. It's irrelevant anyway since
a single 767 strike is different than multiple strikes by 707 or any
other aircraft. The fact remains the buildings were not designed to
withstand a 767 strike simply because 767 didn't exist at the time the
requirement was made.
