Vast Conspiracy? I have no idea what you're talking about. That the names of the supposed hijackers appeared on the manifests only means that the real hijackers stole their identities, and boarded the planes under those assumed names. Or, that some patsies boarded the planes unwittingly, but did not participate in the hijackings.
It's obviously possible. Chuck Pfarrar's book proves that. Didn't you read the excerpt I linked to? How could the passengers notice anything from the back of the plane, if the hijackers bail out from the front or bottom, as did Pfarrar and his SEALS? Obviously, the technique as used by SEALS was designed not to be noticed by civilian passengers.
The planes were flown by remote navigation, such as Global Hawk. The planes may have been assisted to their targets by some kind of localizer or other homing device planted in the WTC buildings and Pentagon.
That technology has been around for at least thirty years, everyone knows that. Even Loose Change knows that.
Most people in the Arab/Muslim world don't think al-Qaeda did 9/11. They readily admit that Arabs aren't capable of such a sophisticated operation. They tried to tell us that, but we wouldn't listen.
You mean his question about remote control? I'll admit I can't describe precisely how a cockpit could be rigged for remote control in 10-15 minutes. But that doesn't mean it can't be done.
You guys are desperately fighting these ideas tooth and nail. But in the long run, you will have to admit that everything I am suggesting is eminently doable.
