Don't you think looking cool is part of making the movie as well? They do need to put butts in the seats you know. Exactly my point. Very plausible. And how many times did Scotty(prime) complain over the years? Sure they did. Why not? It did look pretty cool. No reason was given other than to hide the Enterprise. Because you don't know the reason does not make it pointless. Yup, we can most certainly imply that the reason Kirk put it down there was logical as Spock definitely supported it. Another neat part to that scene was at the end, when the natives drew the Enterprise in the dirt and that silhouette morphed into the real 1701. My only real beef with the opening scene, was the "cold fusion" thing.
