What do you think it is about "quantum mechanics" that so ubiquitously lends itself to being thrown around by so many peddlers of pseudoscience/snake oil who have never taken a physics class?

but then found the manual wheel jammed.

Isn't this a little misleading? It wasn't "jammed" in the sense that there was something blocking the mechanism, it was simply impossible for the crew to operate using only unaided physical strength due to the higher than normal control forces on the stab. If the stab is only trimmable using the same electrical channel that the MCAS uses, doesn't that negate any redundancy in that critical system and therefore present in inherent design flaw? In other words, in what way could these pilots have possibly overcome this situation if they required the very system (electric trim) the checklist called for to be disabled to regain control?
