CT, you say " you can not fly sideways but it sure looks like it". I have a question for you, and I'm not trying to be smart, argumentative or convince you otherwise. I'm just curious. If the FAA Airplane Flying Handbook, the author of Stick and Rudder, any Flying text book you can find (Jeppessen, Gleim etc) says that in a side slip the airplane will move sideways, why would you reject that in favor of what a couple of people on an Internet forum would say? Particularly since they have no authoritative reference to back their claims.
