Look we all know that Startrek11 came up with this kewl idea and wants us all to acknowledge how kewl it would be.
Fine.
The Enterprise has always had vectorable inpulse engines. The thrust output from the impulse array at the aft of the primary hull has the ability to vector left or right by about 5 degrees, and up or down by about ten degrees. (Any further and you'd be risking scorching of the hull, and thrusting against adjacent hull areas, effectively ripping the ship apart.)
The Enterprise also has a NON-NEWTONIAN PROPULSION SYSTEM called "Warp Drive" which is contained in these nacelles.
DO YOU GET THAT? THE NACELLES ARE NOT @#$*ing ROCKET ENGINES!
And even if they WERE, in terms of REAL ROCKET ENGINES, you only vector the exhaust nozzles, not the entire rocket body (which is what the impulse engines do).
The nacelles contain hardware that warps space/time. Yes, even back in "crude 1965" terms, they got that difference. Okay, someone who grew up watching "Go-Bots" and took their main science knowledge from that might not get the difference, but the folks who did TOS, and for that matter most everyone since then. (Apparently Eaves didn't get this, or at least was unwilling to fight too hard against the BeeBs on this matter... since the 1701E has totally nonsensical impulse engine design!)
Here's what >I< think. I think StarTrek11 is making this all up. Alternatively, if he DOES have a friend at ILM (and you'd better be careful, since there are actual ILM EMPLOYEES who read this board and occasionally post here... so if you're lying, it WILL come back to bite you in the ass!) then his "friend" is yanking his chain... and HARD... just to have a laugh at his "friend's" expense.
The people who work at ILM aren't necessarily all GENIUSES, but few are scientific illiterates (ie, they'll never do the sort of GARBAGE we got to see in the SFX sequences in "Armageddon"). And a lot of them are Trek fans.
Would they let ego get in the way of a faithful translation of the original ship design? Quite possible. But would they do something that made NO technical sense? Well... considering how hard they tried to make the freakin' TRANSFORMERS actually work in a logical sense... I'd be stunned if they did anything so unprofessional.
Having the entire ENGINE NACELLES MOVE is technically just total nonsense. Putting the impulse engines on the nacelle ends is also nonsensical.
Might they put small reaction-control thrusters on the nacelles? Sure. It would make sense, just to help reduce the stress on the engine struts during turns. But those struts need to be VERY ROBUST in order to support these massive engine nacelles at the ends. Having that end be made up of some sort of articulation frame simply means that you have a much weakened joint that gives you no PRACTICAL functionality.
The guys who work at ILM (and yes, I have a friend who DOES work there... and I know goddamned well that he can't tell me about what he's working on because if he did, he could get fired over it!) aren't going to risk their careers in a very focused industry by "leaking" important information just so their friends will say "DOOD, U R KEWL!"
