[Strategia_In_Ultima]

It looks wrong? Oh. I just thought it looked nice. But now that you mention it, it does look kind of strange.

Less technobabble, still an explanation:
The Bartelians' on-board computers on Carriers (Carriers, not Light or Heavy Carriers, just Carriers) continually makes slight course modifications to adjust for the spin. Essentially, the ship makes a constant turn left when traveling in a straight line. Not that it flies at an angle; it just compensates continually.
