OK, but that's inconsistent with the rest of the story. If the plan was for the Israeli commando team to take over the plane, point it at the tower (or the Pentagon), leave it on autopilot and jump, they would be at 1000 feet (or something like it), because it would be impossible for the plane to execute a descent from 20,000 feet accurately any way except under local or remote control; an autopilot couldn't do it and be expected to end up anywhere near the building. Correct me if I'm wrong on that. So the possibilities are (please tell me if I missed any):
(1) The Israelis had some scheme to fly the planes into the buildings by remote control.
(2) The planes were never intended to fly into the buildings (so why did they?)
(3) There's some way to jump at low altitude, high speed, when the planes are on their final approach to the buildings.
(4) It was a suicide mission.
Which one(s) of those do you think is likely, and if none, what specifically do you think happened?
