The airplane's shadow appears in the center of the rainbow when viewed from the air. This is because the rainbow is a circle centered on the antisolar point, which is directly opposite the sun from the observer's perspective. The shadow of the airplane falls at this point, making it appear in the center of the rainbow circle.
