On my latest rewatch of GoldenEye, I noticed that when the control room is first shown on screen and there is this huge pan, I noticed that Trevelyan got into the main GoldenEye firing thingy, there was a door between the main console and the monitors, something that would be much more convenient than having to break the glass every time I want to get a large weapon from there. I know that the attachment isn't of Trevelyan entering the control room but it was the closest thing that i could get from YouTube.
