>If this helicopter was then to be put in a sustained roll for a few seconds, the circular ring will now appear as an ellipse. To me, this could be an example of a temporary or cyclical Coriolis.
teetering head, no, the camera must be moved with the spining axes therefore the light would be a circle still.
rigid, mmmmm, i think it would be almost the same, the camera must be moved perpendicular to the spinning axes not just 50ft below the air craft.
