No model, no effects, no cockpit, nothing.
For people who want to make movies while following aircraft realistically, the specator plane has no flight model to speak of but handles much like a plane would and has infinite speed. Can also hover! It has no clipping model so can't collide with objects.
Ok... basically a free cam that doesn't suck as much as CTRL+F11.
It would make following aircaft much easier for those super cinematic shots. Perhaps you could select what 'flight model' it has. From flying brick to large aircraft.
