Default Backwash Causes Lift?

What is the definition of a stall anyway?


An abrupt loss of lift.

I'm saying that, if you take a plane with certain critical angle,
throw away engine, put on an engine that can generate 10x the thrust,
the plane should still fly, even if you exceed critical angle.


No, the thrust of the engine doesn't matter, unless the engine itself
is supporting the weight of the aircraft with thrust (possible in a
few fighter aircraft). A wing above the critical angle will stall at
any speed.

These books imply that the critical angle is angle at with bad things
happen above the wing, and because of that, the plane will fall.


Yes, true.

I'm saying that, you can have all the bad things happen above the
wing and still be able to keep the plane aloft due to compression
that occurs beneath the wing.


The wing is not supported by compression. It is supported by the
displacement of a mass (of air) downward. If this displacement ceases
to take place, lift


This should be entertaining.
