It's all about speed... Force is a factor of area and velocity. That wing is
not a lifting airfoil. It is a fully symetrical surface. At those kinds of
speed, the atmosphere is nothing but a fluid. If you change the orientation of
the wing, it causes a nearly instanteous change in direction parallel to the
chord of the wing.
