the scale of the Galactica is over a mile long .. that is the scale supported by Glan Larson and the model builders and there is a website some where that give all sorts of options on the model scale.
I think i have a drawing some where showing a possible scale for the bay anyway ..
(after a little looking I found the drawing)
the Vipers are to scale as I remember it ..
also the original bay drawing is by westy and he did a calculation once that the landing bay deck is
13 feet below the launch tubes. using the mile long scale ..
