Gravity fails to fall at similar rates of densities. For example the tip of the shuttlecock is being dragged to the Earth. It has a greater density then the feathers and the medium surrounding.
Chronophotographies of shuttlecocks after an impact with a racket, showing the time evolution of the angle between the shuttlecock orientation and its velocity. The shuttlecock’s initial velocity in (a) is 18.6 m/s and in (b) is 10.4 m/s. Credit: Cohen, et al. CC-BY-3.0
