I have noticed that a number of Boeing products have small (looks like 2 feet
or so) vertical fins on the dorsal portion of the Fuselage.  I know for sure
I saw these on a VA B747-200 at BOS.  Methinks they are on 757 type aircraft
as well.  So the question is...what are these things, and what are they doing?
