What's below might be spoilerish if you haven't seen the first nine minutes or read a summary of them. First, I don't know if Orci and Kurtzman meant it, but there's a neat parallel between what Spock is doing in the volcano and what Spock Prime's mission was. Second, the whole thing is so wreckless, which I think it was supposed to be in order to show us how raw (and cocky) Kirk is as a commander. I can't imagine a 50-ish Kirk coming up with a plan like this. So, it's a good scene from that point, too. That said, I do have a couple of nit-picky observations about the scene. The shuttle may not have been built to withstand the heat inside a volcano for a long period of time, but Scotty tells Kirk that if the volcano blows, he's not sure the Enteprise itself can withstand the heat. Hmm. Lava is about 2000 degrees F. That's a little under the hottest temperatures reached on parts of the surface of the space shuttles when they re-entered the Earth's atmosphere. (The most insulating of the tiles were good up to about 2300 degrees F.) So, we're saying the tritanium outsides of a 23rd century starship are no better than 1970s technology at heat resistance? Even for short periods of time? Sulu also says he's not sure he can maintain "that kind of altitude" over the volcano. So, after boldly going to the bottom of an ocean, Sulu thinks he can't hover the Enterprsie above a volcano for a few seconds to beam Spock out? And again, the transporters are no good. Two movies, and two times the transporters couldn't be used when they'd have been most useful. I can see why McCoy never trusted the damn things.
