At Least Two Saudi Officials May Have Deliberately Assisted 9/11 Hijackers, New Evidence Suggests
Newly revealed information also raises questions about whether the FBI and CIA mishandled or downplayed evidence of the kingdom’s possible ties to the plotters.
Hijackers? They weren't flying those planes. Those planes were flown remotely or quite possibly, autonomously.
Some very fancy flying was done that day and so skillfully, a human couldn't have done it.
...highly probable...
...but don't discount the need to have the pilots disabled so that the autopilot programs could be activated without their interference...
Isn't that why Trump went to Saudi Arabia and after leaving one of the Saudi princes was executed by his own father?
