That's a bit different.  In EE terms it's sortof relying on "near field"
effects.  What I was talking about was when the plane was flying well above
the ground.

In your case the ground is so close that the plane pushes on the air, the
ground pushes back on the air, and this effect gets back to the plane in
time for it to "feel" it before it goes past.  Basically the ground stops
the air going down causing its pressure to increase, which in turn pushes u=
p
more on the plane than just the momentum of pushing the air down would if
the plane were higher.  This "ground effect" gets rather complicated.
