On the actual Columbia space shuttle there is on the tail what appears to be a antenna housing which is quite noticable when compared to the other space shuttles. I dont know how to insert a picture but here is the link to a picture of Columbia on landing and if you look on the tail you can see the antenna housing

Just might be an idea on a update or later addon. Either way I'm still happy as a pig-in-$&!#  just to have this fine addon.

Here ya go................

Here is how I set up landings. First I go to the Airport I want to practice landing at, lets say Dover AFB, I pick the shuttle to fly"even though it starts out on the ground with wheels out", next I go under "WORLD" sub-category "MAP", from there I increase the altitude as high as I want and move the aircraft symbol to where ever I want it in relation to the runway I want to land on. Last I increase the speed from "0" its starting speed up to however fast I want to be going. Click ok and it starts you at the position, altitude and speed you customized, from there you can save the flight and go fly it as you set it up any time. Hope that helps a little.
