Hi Zev, What you'll need to do is create a copy of the aircraft subgraph duplicating all the internal nodes of the scene graph, but share all the StateSet and Drawables. This way the light parts of the scene graph that need to have individual values like the transforms can have their own values, while the heavy memory wise stuff - geometry and textures can all be shared.
