It's been a minute, but I believe all but two were Saudis. Unfortunately, all the evidence is suspect. The source material just cannot be trusted.

The airliners were most likely remote controlled because at least one of them pulled a perfect descending corkscrew maneuver in order to be able to hit one of the towers (that's why it impacted the tower while it was rolling to one side).
This implies no hijackers were needed to control the plane.
Now you lost me.
All thing being equal the simplest explanation is more probable. Suicidal freedom fighters were abundant. And Americans are docile and submissive to highjackers and other criminals. No wiring necessary.
Thanks for sharing your thoughts.
