The World Trade Center never actually existed. Heck, New York City is nothing but a huge scale model of what such a city WOULD look like, so all the government did when they flew their model planes into the buildings was destroy a few thousand dollars of materials and man-hours.
It's all part of a vast plot. The model's janitor, Rudolph Giuliani, pretends to be the mayor of a non-existent city just so he can have a platform to be chosen in a rigged election to be CEO of the company so he can gain a monopoly of the model-building industry for whatever shady organization he represents.
