The problem with that is the collapse would be dramatically slowed. If it was just a weakened structure collapsing under its own weight some floors would have held out for a bit. What are the odds that every floor was totally compromised and provided 0 resistance on the way down? There IS a way to do this, of course, with controlled demolition. But I refuse to believe "slamming a fire into the 100th floor" and "meticulously planting timed charges on every support column" yields the exact same result. Also do you truly think there was a window big enough to fly an airliner through
