CIC is the Combat Information Center. During military attacks, all relevant information about target locations was fed into this room.
The room is notable for the special lighting that was used to make it easier for the men to see what was happening around the ship. This page has several photos of the CIC.
(It also has photos from a number of other locations on the ship, so you can see what these areas look like with the lights on.)
Clip 1: In this clip, you’ll hear me comment that, in a short while, all the men who once knew how to use all the equipment in the CIC will soon pass on. There is a constant beeping noise in the background that is coming from something inside the CIC. At the 12 second mark, a male disembodied voice whispers, “Fuck you, then.”
Clip 2: In this 2nd generation recording, Laura J is tagging the location for her audio recorder. At the 4 second mark, I can hear what sounds like disembodied voices speaking but I can’t make out what they’re saying.
Clip 3: This is also a 2nd generation recording. Laura J asks, “Can you tell me what Sinbad 617 is?” I can hear possible disembodied voices after this but can’t make out what they’re saying.
