In the UFO TV series, the pilots of the moon based interceptors are always shown entering a slide which presumably takes them from one of the habitation spheres directly to their ships. The ships are then raised from an under-moon storage area to a series of side-by-side craters in order to be launched.
But in all aerial images of the moonbase itself, there is no indication that these launch silos are anywhere near the moon base. And the base itself is never alluded to be anything bigger than what is shown.
So where are these silos located in relation to the moon base?
After recently watching all 26 episodes this aspect just never made sense to me (and no, that is not the only things that doesn't make sense in-universe)
