As for the three port holes on the front of the primary hull, we never saw what they were for... they were dark in the first pilot, the center one became a navigation light in the second pilot and they were all lit like the other windows by the time of the series. I left the space behind them on deck 6 unoccupied.
Because all the windows we saw from within the ship were rectangular, I'm treating port holes as something else other than windows.
- Great work as usual. Better watchout or we will start to expect it (kind of like Dan Aykrod's line in Ghostbusters "You've never been in the private sector; they expect results.").
I know it was all stock footage, but the use of the middle light as a navigational beacon was not limited to the 2nd pilot. I remember seeing it in "Mudd's Women" and going WTF? I had thought they were just windows or something all this time, I get a copy of the epiosodes on DVD (non-remastered) and see this navigational light. Again, not faulting you for namingg every single episode in which it appeared dark, blinking or on (we'd be here through the next decade if we did that kind of thing), but just an FYI to point out that it was still a navigational deflector in at least one other episode in case you had missed it (took me 30 years to catch it and I am usually good at catching things like that).
