Airplane mode on/off
Most smartphones these days have a button/setting to switch off (and on again) all radio transmissions when on board of an airplane, to prevent interference with the on-board electronics of the airplane. I would like to see created two icons showing an airplane with the difference that you're either ON the plane, or OFF the plane. This means in picture/icon terms: airplane with ON text in it equals to all radio communication of the smartphone is OFF. Airplane with OFF text in it equals to all radio communication of the smartphone is ON (again). I cannot describe it any clearer. Thank you for these two icons!
