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.
