Good stuff, and it's prompted me to get back to a couple of similar projects, when time allows.
I've planned a couple of boxed dioramas, with the 'action' taking place within a Perspex box display, with a sky and horizon background, and 'terrain' base, to scale in relation to altitude. The model(s) will be either on clear acrylic rod 'sticks', or in some cases attached to the rear of the 'box', to give an 'in flight' appearance.
