In that specific video I pushed the turbulence up considerably - Wind/gusts to help emphasize the planes moment in relation to the the cameras.
Currently the camera is locked to the axis of the plane. so if you bump up or down the camera moves with the plane. In this video i used the Drone camera to show how it would better work for VR users.
Take 2 minutes to go to the bug feature set and have a read through the original posters explanation.
