The very efficient wing allowed the plane to carry heavy loads. But even a
cocktail's worth of ice could severely degrade the wing's lift. The B-17
has a less advanced wing, the upside of this was that it could tolerate
considerable icing before it was severely affected.

I think the same was true of flak damage.
