Default Backwash Causes Lift?

If that is the case, what is pushing the air?


You may be able to get past this by considering that the airfoil
actually turns the flow, rather than push or pull it. It turns the
flow downwards, and this acceleration of the air mass engenders an
upward force that is lift.


Mmm, nope.
