I'm leaning toward this, at the moment. Interesting notions there. This could help explain why the "southern" bay was so different indeed. Not just a support bay for herself, but for other small ships too. I kinda like it. Interesting. I didn't know Mr. Probert regarded it that way. I always tried to mitigate the notion that it "failed" by saying that the result was a conventional system that was still light-years better (no pun intended) than conventional warp drive. I'm in the minority, but I've always interpreted transwarp to be along the lines of a jump drive. Styles' lines in TSFS might seem to agree with this. Then again, the line "All speeds available through transwarp drive..." is a tantalizing one. (And, I concluded transwarp to be a failure by the fact that they didn't call it transwarp on TNG, and later by the fact that other races had something called transwarp.) So in other words, you're contending that the module is the transwarp drive system, which was in fact successful and later revised for other ships into something less... modular? But for the Excelsior class, they had to remain with this odd semi-vestigial modular weirdness? Agreed. Why can't there be other drydocks? (This is something I've always assumed to be the case.) In Generations, we see an apparently larger one inside of which the Enterprise-B was built. Perhaps it's the same one in which the Excelsior was built? I don't think we can rule that out... but somehow Spacedock has always seemed unlikely as a starship construction facility to me, given what we saw inside. Still, I don't think it can be ruled out. And, I've never considered the possibility that Rand was on Excelsior, especially given we see her in San Francisco in the next film. I always assumed she was assigned to Earth. Then again, in TSFS she appears to be a Commander, so she might have a twin sister. Thank you for providing that sir. I might have to take some very rapid screen caps and alter the levels similarly to see if any more light can be shed. It appears to me as if there is more of a reinforcement around the pod in this version - which should come as no surprise since I believe this model was made from the Jein version, which did have a slightly different structure inside there. I'll dig up pics later. Fascinating explanation... thanks for that, too.
