Good point, Ernest. Forgot how far forward the inlet was on the ME109 - not
been watching enough late WWII movies {:>).

The scoop is right at the the front of the plane. The boundary layer is
going to be almost nill there to begin with. Compound that with the
fact that the air has been accelerated by the nose curving up, and that
the nose will be high when the cooling is need the most (climbout), so
that the air is injested more directly.
The problem with the P-51 was that the scoop was much further back on
the plane, and the boundary layer had time to grow before it got there.
