Like a rollercoaster...

Hi
Has anyone noticed that if you put smoke on in a plane and watch the replay then the smoke is already there, looking at it from the cockpit looks sort of like a rollercoaster effect as your following lines.
I noticed this with the Harrier, not sure if it works with other planes.
