It's noticable that those who are under the spell of this nonesense are not addressing any of the simple logical quesitons that are being asked in this forum.
Here's another for you to ponder. Which airline in the Western World these days is not under strict guidelines that prevent members of the public, or even cabin crew, entering a plane's cockpit ? Answer = none. Now before the believers say 'it was an emergency situation'...let me head that one off by asking you to decipher the fact from fiction for a moment and recall that it wasn't ever an emergency, it was acted, and we were told it was being acted.
So, the only way Matt or the crew could have got into cockpit was if that part was filmed when the plane was on the ground. Did they have the wool over his eyes on this too ?
