The "evidence" in this story hinges on an eyewitness who says the people in the Learjet flew out on a 727, then from there they come up with names? While I think this Learjet flight took place, the chain of evidence is weak, at best, in regards to who was on the plane.
No, I believe the names came from the manifest of the 727. There were only three people on the 727 who had Tampa addresses:
Of those, three listed residences on Normandy Trace Drive in Tampa, and all of them held Florida drivers' licenses. They are Ahmad Al Hazmi, then 19, Fahad Al Zeid, then 20, and Talal M. Al Mejrad, then 18, all male Saudis.
