Continuity mistake: When Barf and Lone Star are rescuing Dot and the princess for the first time (from the Mercedes), they position their ship over the Mercedes but facing the other way (ie. facing Spaceball 1). However, in the interior shots showing Lone Star in the cockpit, the view is just clear space. Spaceball 1 is a gigantic ship, and they are very close to it (as well as angled slightly up to it), together with Spaceball 1's "mouth" being open which makes the ship even bigger vertically. It should block their entire view, but it's not seen at all.
