People realize how easy it is to “fly” in space right? You don’t have to to be Superman or Mary Poppins. It’s space. People realize this, right? Right?
This is one area where Star Wars has always done whatever the hell it wants, physics be damned. Constant thrust should equate to constant acceleration, but in the Star Wars galaxy ships fly at a constant speed no matter how much they run the engines. In a fully realistic version of the Leia scene, the increasing acceleration of a cruiser constantly firing its engines would soon overtake the body of a person traveling at a constant speed due to an explosive decompression.
