I'm not sure "TOS:Tomorrow Is Yesterday" is the best ep for proving the 1701 had no anti-grav systems.
Right, and I don't think we can rely on the old "they never mentioned it-therefor it does not exist" argument. Personally, I'm hoping to see some new and awesome stuff in this movie, not a technical journal of TOS technobabble.
In any case, they HAVE artificial gravity. anti-gravity is probably the same thing turned upside-down with the wires crossed. (How's that for scientific predictions?)
Quite likely. You'd think a system that spans every deck of the occuppied volume of the ship could well have a secondary mode for what would be mostly emergency situations when gravitational forces acting on the ship need to be offset.
The fact that the ship is never intended to land on a planet's surface doesn't preclude it having the ability to cope with in atmo or low altitude scenarios when required.
I know Gene R. made reference to "unit components" constructed at the San Fran Yards followed by orbital assembly. What are the unit components - the individual hulls and nacelles? Seems they'd still need anti-grav hefting to orbit (even I'll balk at anything that big being transporter friendly, at least in the TOS era). Any systems benefiting from micro-gravity conditions would probably already be assembled before this point, and if you have the tech to reproduce micro-grav on the ground while retaining the advantages of working in a shirt-sleeve environment, wouldn't that be the go? (we don't see any fully enclosed spacedocks before ST:III, discounting FJ's non-canon Fed HQ, with no indication that even the dock area there is or can be pressurized, though anything's possible I guess)
An all up ground launch would conflict the above, which is essentially a production note, but no on-screen reference, so I suppose it's all a matter of where you draw the line. I'm also quite happy with the trailer sequence being entirely metaphoric by the way. There's a dream sequence feel to it that seems to allow for that whole artistic licence thing, so nothing's probably etched in stone yet in terms of what the gen pub has laid eyes on.
To say we can accurately scan ahead with our early 21st century crystal balls and firmly eliminate any mid-23rd century tech scenario is on par with what late 18th century "technocrats" could predict about what we'd be up to, and that's not allowing for the accelerated pace of many recent technical advances. In 23rd century terms, aren't we all scientific illiterates?
The forty years between TOS and now should allow for a little "wiggle room" in how the future is portrayed. Dogmatic clutching to one set version of "predicted" events is , well, dogmatic clutching.
It's science fiction Jim. Enjoy it.
