 CONT: In the title sequence you see a Nimitz classes aircraft  carrier putting to sea going under the Golden Gate Bridge, this shot  being taken from the north side of the bridge. In the next cut you  see a Nimitz classes aircraft carrier putting into San Fransisco,  this can be deduced as the shot has the Presidio in the foreground,  which is at the southern end of the Golden Gate Bridge, and the ship  is moving left to right
