A terror attack without explosives is like a pancake collapse without the pancake

 http://en.wikipedia.org/wiki/Geologic_fault
Even as the official story goes, a "pancake collapse" would have required grave manipulation at the very basement of the buildings to bring them down.
Perhaps, there was just an earthquake at the same time so that the earth miraculously opened up and sucked everything in like a caldera, except for the pilots and passengers who have been abducted and eaten by aliens who were just stopping by to say 'hello'. No, we're not angry nor mad, we simply want to figure out what really happened and continues to happen.
And why the health would anyone declare a war on terror if the alleged terrorist incident was just an unpredictable accident or an inevitable natural disaster?
Make sense?!
