I don't have a copy of Ep. I to check the yacht scene, I'm afraid, but I shall look it up especially since I do not recall such an observation. The Ep. II reference also escapes me. In the interest of fair consideration, I'll see about renting them.

I've had similar discussions on the Starship Modeler forums; in fact, there's one going on presently. I tend to play devil's advocate in such chats. There's a fine line between dazzling someone with real-world numbers and making unfounded claims.

Does anyone else listen to Kajagoogoo's "Too Shy" and think of "Save the Earth?"
