You could shine a bright flashlight or laser at the airplane – this has been known to get pilots’ attention and make them change course. Alternatively, you could look for patterns in the sky such as stars and constellations, or reflective objects like mirrors or shiny Mylar balloons, which may be more eye-catching and easier to spot from a distance than standard lights.
