What kind of space ships can make banking turns?

No kind of space ship can making banking turns in space. When an airplane makes a banking turn, it does so by deflecting off a cushion of air. The air redirects the plane's momentum in a new direction. In space, there is essentially no air, so space ships cannot make banking turns. In order for a space ship to turn, it has to fire a rocket sideways to reorient itself, then fire its main engines to begin traveling in this new direction. But because there is no air to redirect its momentum, a space ship still has momentum in the original direction. The result is a graceful, slow, arching turn. In order to get rid of its original momentum, a space ship would have to fire rockets in the opposite direction that it was originally traveling. The bottom line is that banking turns are not possible in space. Dogfights between enemy craft are only possible in the atmosphere - not in space. Hollywood tends to distort this principle of physics in order to make space battles more exciting, as well as to appeal to viewers who are accustomed to watching aerial dogfights that became the stuff of legends during World War II.
