In fact every impact point of both the towers and the Pentagon struck at the very points critical data was housed. If you research the floor levels that were hit and the area the Pentagon was hit, ALL had important data on the missing 2.3 trillion DOD budget, the Enron scandal, BCCI scandal and much more!

As in the Pentagon, it had just literally finished an extensive renovation to make the area stronger, the hole left in the building PRIOR to it falling down was only about 16 - 20ft in diameter, and left a smaller exit hole in the inner wing (either C or D I can't remember without checking) of about 8ft diameter. The offical story was that somehow the entire aircraft melted to a liquid slug, went around many of the supporting pillars and brickwork, before reforming to a slug to make the exit hole on that inner wing! Serious, that's what they say happened to a 100 ton airliner! Each engine is about 6 ton of steel and titanium!

Building 7 also housed some very interesting agencies, and I believe was supposed to be hit by flight 93 but something went wrong, so they had to bring it down with explosives pre planted and tried to blame it falling at free fall due to a few small office fires. The only time in history were steel framed structures fell due to fire and they all happened on the same day!
