'superstar destroyer' doesn't quite work

;) I think the "official spelling" now is, Super Star Destroyer. I actually think it should be Super Stardestroyer. I looked around and saw that wookieepedia says that the spelling Stardestroyer is wrong in the DVD subs, in my mind it's correct, it is just a destroyer like the real ones used in WWI & II but among the stars, not something that destroy stars. You don't type Sandcrawler Sand Crawler, Landspeeder Land Speeder and Starship Star Ship. Also the first time I saw Sandpeople spelled Sand People was around '97 on the soundtrack CD.
