Abstract	Sometimes it takes little to keep this physicist happy on an airplane. A window seat, where the plane's shadow is visible or has disappeared into the distance, provides the opportunity to observe a variety of phenomena associated with sunlight that is reflected, refracted or scattered back towards the Sun. The term "backscattering" is often used to describe these phenomena. The Sun, me, and my position in the plane's shadow (called the antisolar point) are all in a line. The backscattering phenomena are at or centered on the antisolar point for the observer. If you can see clouds and their shadows on the ground, figure out where you must look to see a cloud cover its own shadow. That is where you must fix your attention to see these phenomena. (As Provided).
