I've found two trailers online, one is youtube (crappy lighting) the other has better lighting. If you hunt around you should find it.
Good trailer, actually get to see parts of the (under construction) Enterprise.
I thought the welders & workers on the hull were great, so these are the guy's & girls that actually build the damn ships. I guess Scott is down in that construction mess somewhere overseeing things, the trailer made 'Trek' just a little more real, hope they keep it up in the movie.
