I wanted the hangars interior to look like the drawings of Andy Probert used as trompe-l'oeil on the original model of the Galactica (provided as 2 decals in the kit ).
It was necessary to translate and extrapolate the drawing while playing with the small space, the lighting, the discordant scales between the drawing, the hangar and the viper launch tubes (on the exterior side).

My blueprint is drawn directly on the part floor. I only use half the hangar lentgh, as the metal bar cut it in the middle.
It will be lit in white above the runway and red on the sides.

On the workshop side, I added greeblies along the wall.

And on the other side (with the launch tubes alcoves), the wall is rather smooth, so I added some paneling.
The trapezoidal openings are aligned to match the outputs of the launch tubes.

The ceiling of the runway is a clear plastic card, frosted with sand paper, detailled with Evergreen plates, behind which will be later placed the leds in indirect lighting.

The ceiling of the workshop is a ladder covered with frosted transparent plastic, which will be painted Red Clear later. The LED will later be placed on top.

For the LEDs to not move and remain in indirect lighting, a housing is created with plastic card above ceiling to lock them.
