See Custer Channel-wing [Google] and reaction controls.

apart from

any airflowing

is not

backward force, as i

get you

| It however, would be possible if you have a plane with an
exceedingly
| small wing span, very low stall speed and a big propeller
to generate a
| downwash to cover the entire wing. As you know your
aillerons are

downwash
| over them it will stall and not turn leading to a
temporary lift and
| then crash.
