To understand a little how the UFO FDM works, and to be able to apply it to other projects, such as the TARDIS; in the meantime, when I took over my 3D projects, I came across an old 3D model that I worked on several years ago and that lay silent among my data. To the typical capacities of the UFO, that is typically installed together with FlightGear; into this 3D model has been added some animation and a system of concealment "CLOACKING Device" of the flying disk. I'm also working on the possibility of creating a cockpit for a pilot who has access to a dashboard with instruments. So the interiors.
