I've come to two conclusions after reading through this thread.
One, christophera has much better eyesight than me.
Two, christophera is not from this planet.
Christophera, you do realize that your theory is just as plausible as saying this:
It was actually aliens that downed the Towers with some type frequency modulation device. The device is so precise it will calculate the exact resonance frequency of a large structure in a matter of seconds, then send out pulses that subsequently destroy it. It is also able to be so precisely controlled that the aliens were able to make it look like the building fell at free fall speeds simply by using the gravity-multiplier ray option from the Intergalactic Arms Association. They knew the near free-fall speed would catch the eyes of a select group of individuals who would go on to make money writing books about it pinning the crime on the US government.
The aliens command of mind control was used over 30 years ago when they implanted the design for the towers in a few individuals heads, knowing that about 30 years after construction they would revisit earth and force unwilling Muslims to highjack planes and fly them into the buildings, which would become an oh-too-convenient alibi for the aliens. (Notice how no one except me has figured out that aliens were behind the entire thing!)
A certain race of aliens ( I will not go into discussion about that here) have been avid baseball fans for decades. When the Dodgers beat the Yankees 4-0 in 1963, the aliens knew something was up. Their investigation ultimately led to the discovery that the game was fixed, and a few 'elite' people were behind it. These same people were involved in land development deals around Manhattan, and guess what project they were about to start work on????
Yup! The WTC's.
That pretty much sums it up. The aliens were pissed at a few individuals, and decided to take revenge. But wait, it gets a little creepier.
Why 30 years later? I'm glad you asked. This same race of aliens is know for it's ability to see into the future, but not more than 35 to 40 years, which turned out to be plenty of time. The aliens saw that a parcicular decendent, whom I will not name here, of one of those 'elite' idividuals would discover an actual starship in a cloud by viewing it from a telescope from the 84th floor of WTC1, ON SEPT 12TH, 2001. Not only would this individual make the discovery, but the individuals involved in the fixed game would be in the towers on the very same day.
This individual who would have discovered the ship on Sept 12th 2001 had an injury which prevented the aliens from using their mind control abilities. The metal plate in his head simply didn't allow it to work.
So what better way to take revenge on those responsible for the fixed game in 1963, and prevent the discovery of one of their numerous starships, than to destroy WTC1 with the discoverer inside? Problem is a clerical error caused them to take down the wrong building first, hence the delay before actually taking down the correct building. I don't have to tell you that during that delay plenty of aliens lost their jobs on that one!
I couldn't tell you what happened to WTC7, it's just too strange an event.
