You miss the point. If the Colossus has 30.000 crew and the Orion 10.000 crew and nobody hardly disputes those facts, why should anyone dispute the Sobek of having 6000 crew (hell, its as canon as both of those previous numbers)? The crew numbers are not linear and seem to decrease in crew/volume as the size of the vessel increases.
Becouse those numbers make more-or-less sense and have appeared SEVERAL times, thus meaning that the probability of mistake is nearly non-existant.
The sizzler
If [V] wrote it in and it got past all the testing and editing, then it is canon. No question about it. What you're doing is like saying Han Solo didn't get frozen in carbonite in The Empire Strikes Back
So if [V] wrote in one of the briefings that you have to rescue 4 transports, but only 3 appear in a mission that would not be a mistake but a cannon fact?
While the number 6000 has it's weight simply becouse it appears in a SINGLE debriefing (one that you're HIGHLY unlikely to see), you cannot deny that the number is strange to say the least. I have no proof that this is a mistake, but then again, to form a oppinion I don't need rock solid proof, just a strong indication of something.
Oh - people keep pulling out some carrier numbers. Here are a few exact one:
Carriers usualyl have 5000-6000 people on board and htey carry 80 fighters:
USS FORRESTAL 2900+2279 fligh crew
USS ENTERPRISE 3215+2480 flight crew
USS NIMITZ 3184+2800 flight crew
As you can see, the flight crew is pretty big. 10000 for a destroyer sounds acceptable - 150 craft compared to 80 of normal carrier would give you a number of 5000 fligh crew for a destroyer. The rest are tending the ship.*
So if a destroyer needs 5000 pople for the ship alone (not fighters) how the hell can a corvette require more?
*assumption made that the number of personell per craft remins the same, which highly likely.
