Up in the air I saw them, all during the day and the night, too, plus these things called hellacopters which are smaller and noisier and don't fly as high. I don't know what makes them fly but whatever it is must be bad, like the stuff that muggles used for autos and to heat their homes. Because the aeroplanes left giant plumes of smoke across the sky, and the smoke would stay there for a long time after they were gone.
