I don't believe that the boundary layer has a significant effect
here, as it is too thin (compared to the aircraft size) to be
noticeable.

According to "Meteorology for Scientists and Engineers", by Roland B.
Stull, the boundary layer is about 2 km in height.






Hmm.. that must be a different boundary layer from what I am thinking of. A
boundary layer to me is the transition layer between a free flowing air and
the staionary air next to the surface. On a flying surface this is just a
few millimeters thick.
