I've noticed some discussion in this thread about the plane supposedly flying to 45,000 feet, perhaps as a way to induce hypoxia. Earlier in this thread, someone posted a link to a disaster where an engineer, after a repair, set the pressurization system to manual instead of auto. The pilot didn't notice that it was set to manual after takeoff. A slow depressurization resulted, and everyone passed out. The plane crashed into a mountain. My point is, there would be no reason for the plane to ascend to 45,000 feet if the pilots/hijackers were already in control of the pressurization. They could simply set the system to manual, change the parameters, and suffocate everyone in the plane except themselves. Not only that, but rapidly ascending to 45,000 feet followed by a plunge to 20,000 feet seems rather unbelievable unless there was a struggle in the cockpit.
lol, I have the same Saitek yoke
