Well the aliens do the surprising element side of their mockery what earthlings have it as their commonest silliest stupidity. What we humans diversified civilizations do or were doing were calling them over some communication link since 1996 and then they just logged into earth zones. And some stand in as the interpreter between what they other planets say talk and what earth people understand. So CIA findings seems like coded messages like or some talks. U mean the 4th plane was downed by the crews/passengers who resisted the hijackers who didn't knew to fly these planes. (in our newspapers it was written f-16 had downed it). But if u see the ascend, descend and angle of the planes these only are known by real pilots. But i am still baffled as how they turned these planes to UFOs!! Or how the planes dissappeared and in their place UFOs appeared. Perhaps some encrypted decrypted messages had hit the twin towers computer earthlink satellite systems terminal transponders from the alien mother ship in 1999. But everyone denies it as they never knew or understand it. Perhaps the alien mother ship their energy beam over the twin towers buildings telekinesis in some souls in their sleeps and elevated them into the mother ship. And later brought them back at some other point of time in say 2006 2009 in some dessert isolated villages of america. Erased their memories that they never remember who they were or where they had been.
