   Most aerial films have a very high saturation to overcome haze and
fog... I think Kodak used to have something called SO-411 which was an
excellent example.  Another good example is a Kodak photomicrographic film
(not a special order), which is (or was) an E-4 film at 6 ASA which
offered extreme contrast and saturation.  Actually, you can get pretty
good aerial results with K-64.
  The main reason is that light up there has not been diffused by the
atmosphere and is much more directional, which seriously increases
the contrast.  When combined with relatively high-contrast film,
you get great results.
