Trying to figure out what happened is impossible because we don't have the proper access to the people, documentation, etc... It's like trying to put a puzzle together with half of the pieces missing. Every "answer" we have as to what happened is just a "theory." Some are better than others,
That is the kind of statement that makes me want to ask, "Did you ever take a course in physics?" About two weeks after 9/11 after my brain started running again and I kept asking myself, "How could those buildings fall straight down?" A demolition really hadn't penetrated my thinking so I was trying to simulate in my head how a plane could do that. All I could imagine was the impact doing enough damage to cause the section above the impact to fall toward the impact zone and to the ground as a solid chunk.

Once it is irrefutable what happened that should narrow down who could have done it. Trying to go by motivation would be too speculative.

30 years before the moon landing engineers without computers could design machines that flew thru the air at 400+ mph. It is now 37 years after the moon landing. We have computers coming out of our ears. Why can't everybody figure out that the automobile is just making useless variations in machines that roll along the ground at less than 130 mph? Is it surprising that these people can't see an airliner can't knowck down a skyscraper in less than 2 hours?
