Huh?  I flew low altitude routes in the Navy and never heard anything about special physics and aerodynamics.  If you leave out ground effect (which every pilot should know about with or without military training) the only special physics I know about is that a/c don't fly well through dirt.  I don't think it takes special training to figure that out.
