Well, from other modelers I've spoken to or corresponded with, this wasn't an isolated event. It apparently happens with some frequency at IPMS contests.
Like I said, I'm well aware that "real space" isn't the most popular category for folks to enter, at least in this day and age. Although it is probably one of the most active subjects for modelers online and the aftermarket and garage-kit manufacturers are producing some really fine stuff these days, it is still much easier to do a contest-worthy Sherman or F-16 or whatever than it is to do an accurate shuttle or Soyuz or Gemini capsule. And with a few exceptions, most of the judges are out of their element when it comes to judging this category. They may know the exact color of the cockpit of an Fw-190, but when it comes to what a surface covered with AFRSI should look like or what the inside of an SSME looks like after firing, they're clueless. Like I said, there are exceptions, and there are some judges out there who can actually teach you some things about real space modeling and I appreciate their efforts.
It would be nice if more people built real space models so we wouldn't have to have discussions like this. (Hint: There aren't many entries in the category, so it's easy pickin's, guys....) But that said, it's unfair to judge a shuttle or anything real in the same category as a Gundam, as in the example I gave. You're comparing reality to fantasy.
I don't mean to take anything away from the guy who built the Gundam or the other kits in this particular contest. The model was very well done, for something make-believe. If I build something sci-fi or of a fantasy nature, the Gundam would've been a worthy competitor. But I didn't. I built a model of a real vehicle. You can compare what I built to the real thing and make your own judgment as to whether I did a good job or not.
I know a lot of this rambling sounds like sour grapes. It isn't. I'm just trying to point out that there is a categorization system in these contests that A) creates an applies-to-oranges competition, B) the folks in charge really don't seem to care and C) when the results discourage real space modelers and they stop showing up at contests, everyone wonders why.
