Now that I am viddying these fine examples of art down there at the fan art section, where they speculate (and back those speculations with awesome cgi) where everything is inside the Enterprise, and also the Shane Johnson book I avidly read back then,.... ... the airlocks placement dont make a bit of sense. Why would anyone choose to board the ship in the middle of the cargo deck where there is nothing besides a corridor from the side of the hangar bay to somewhere else (ok, there is a turbolift, but so far from the more useful places). Or the side of the fraking torpedo room? what is in there except crampiness? An there is tho one at the back of the bridge. The most busy place in the ship where visitors have, in principle, nothing to do.
