Rincewind is saying the same thing Will Smith’s character’s says in the 1996 movie Independence Day upon admiring a new piece of technology, after having just blasted off into space.
As an afper put it: “The contrast between Will Smith (“I’ve got to get one of these so I can fly around blowing up aliens for God, motherhood & apple pie”) and Rincewind (“I’ve got to get one of these so I can run away more efficiently”) says (to me at least) that this has just got to be deliberate.”
Terry later confirmed that it was, indeed, a deliberate reference.
