Enterprise-A is built in the Yorktown docking tunnels..
Thus in space, making Scotty a liar.
..and during her construction we see many little people standing and walking along her hull. So she's built in one-gee of gravity, as the Enterprise was.
We see people walking on all the starships ever built. Usually inside, but sometimes outside, as with the E-nil-refit. So the ships can withstand one gee of acceleration. Big deal - and by that I mean such a small deal that it does not appreciably differ from zero.
If a ship cannot withstand one gee during construction, she's not a starship. If a ship can, that still doesn't win her any prizes. In other words, the difference between built-in-space and built-on-ground must lie elsewhere altogether, and we just have to figure out where. Except we don't, since there is no difference in evidence.
Because we never saw it until now.
What, mastery of gravity? We first saw that in "The Cage". You know, the episode that established that starships indeed exist, indeed can defy gravity and most laws of nature at will, and made it clear that if a starship ever were to have trouble flying through an atmosphere or indeed a mountain, something must be terribly wrong with her.
Yorktown is simply a masterpiece to hammer home this point for those who for some reason might have missed it.
..them being incapable of the larger and more spectacular Yorktown it is a far from definitive, but still a perfectly valid one.
That misses the mark on two sides at the same time. Yorktown vs. Regula 1 is not a big deal, just a matter of quantity. But neither Yorktown nor Regula 1 represent the best that Starfleet can do, because starships are automatically better. Not only do they create (and withstand) one gee at will, they also create (and withstand) impulse accelerations that must amount to hundreds and may amount to tens of thousands of gee.
That they can hover is not in question - they can maintain arbitrary acceleration for weeks without effort. Whether they
do hover is debatable: "standard orbit" in TOS is IMHO best explained as hovering. But an incredibly powerful argument would be required to establish that hovering inside an atmosphere would be more difficult than hovering outside an atmosphere, especially since there is no in-universe example of it being more difficult.
I think you're confusing the way you like to imagine the Trek universe, and the Trek universe as it appears on screen.
This is something I often hear from you in particular. It has never been true, though. Onscreen takes precedence, and once again you are in contradiction of it.
That is, you are the one turning a blind eye on the absolute ease at which starships of all eras handle atmospheres, without contrary comment. And then you cling to a single piece of dialogue that may suggest otherwise, failing to notice that there doesn't exist another such piece in the canon of Trek.
On-screen, the Franklin's transporter was cargo-only (exactly as everything prior to Enterprise NX-01's in "Broken Bow" was), and Scotty upgraded it to beam 20 at a time because he's Scotty.
Considering how full of shit he was in this movie, he probably didn't.
So really, you're saying every time they've suggested in-universe that ships aren't meant to fly in atmo they've been wrong.
Yup. Both in ST:Beyond
and in ST:Beyond. And, you know, ST:Beyond.
It's a fair observation of a flaw in Trek's world, but it in no way reflects the in-universe opinions of the characters or the intent of the writers.
It contradicts Scotty, who is wrong as we soon see in the movie itself. It is in agreement with the expert opinions of all those heroes who took their starships to atmospheres with no comment whatsoever, or indeed with encouraging comments, and especially with all those events where very special circumstances (deliberately suicidal flying in "Arsenal of Freedom", a clever maneuver by the habitual atmospheric maneuverer Ransom combined with weapons fire in "Equinox", etc.) are absolutely required to make the dip dangerous and the danger goes away whenever our heroes or villains so wish.
I don't think I'm contradicting any writers other than those of Beyond if I'm accepting all those other episodes and movies as written!
