Excellent post ellindsay!
Yes I am aware that the 9/11 planes were older types, not FBW. I remember that on the forum in Holland, on which discussion my blog is based, we had heated debates over exactly this issue. You will probably agree that an autopilot controls servo's that control the cables. You confirm what somebody in Holland stated: that the steering pole (german Steuerknueppel; english word?) follows the movement of flaps (word?). What I cannot imagine that there is no mechanical amplifier between the steering pole and the planes that are controlled (a wing and tail). The forces on these planes at 500 mph must be enormous. There must be an amplifier. If that were the case then I cannot accept your reasoning that the pilot can 'mechanically overrule' the autopilot. It is the force of the servo that determines the position of the flaps
But I get your point and start to understand why in the narrative of 911research they build in an additional element:
The use of AAL Flight 11 and UAL Flight 175 to attack the Twin Towers, and of AAL Flight 77 to attack the Pentagon requires the execution of two main tasks in each case:
1. Rendering unconscious the flight crew and passengers, preventing any communications from them about events in the cabin.
2. Taking over the flight computers, allowing the planes to be auto-piloted to their targets.
Task 1 is achieved with aerosol bombs of decapacitating gas hidden in luggage. The gas is fentanyl, the extremely potent opiate used by Russian forces to end the hostage crisis in the theater in Chechnya. The bombs detonate when the barometric trigger senses a cabin pressure corresponding to an altitude of 28,000 feet. The fentanyl gas diffuses throughout the cabin and is absorbed so rapidly by the victims that they cannot even pick up a cell phone or handset to initiate a call.
But I am starting to feel compassion for you debunkers. We truthers are hopeless.
