Default Backwash Causes Lift?

However, that mess will be less than
static pressure, and there will still be compression beneath the wing.
So if thrust is great enough, airplane should be able to do whatever
it wants.


Pressure beneath the wing is not what lifts the aircraft. It's the twisting
acceleration of air above the wing downward that results in lift.
