The making of you can see here in this video captured at the Siggraph 2011. Where the director Damian Nenow explains about where his inspiration came from, cloud simulation, 3D rendering of the cockpit etc.:http://motionographer.com/features/damian-nenow-at-siggraphpaths-of-hate/To me 'the making of' are usually more interesting than the actual film. It looks like they used a simulator but the studio created everything themselves.Pic
