Machinbird, these guys are not psychos. They are smart operators who have figured out that they can sell DVDs by creating controversey. They do harm and should be opposed.
My revised calculations show that the plane would have to be banked at 77degrees to perform the proposed ridiculous turn with a g-force of 4.4.
This leads to an interesting question. What is the maximum bank angle that a B757 could fly at and maintain height?
The maximum legal bank is arrived at from the maximum legal load, 2.5g, about 66 degrees, but we don't want to apply this restriction. The question is really about power. At maximum power, what bank angle could it get to and maintain height, assuming it did not break up?
I presume it could be worked out knowing the max power, and the drag at various AoA, given that the AoA and bank angle must be related in a level turn.
Any takers?
