What is the best strategy for signaling for help when stranded?

Using reflective materials or creating loud sounds is indeed the best strategy for signaling for help when stranded. Reflective materials, such as mirrors or shiny surfaces, can catch sunlight and create visible signals that can be seen from a distance, especially by aircraft or ships passing overhead. Audible signals, like whistles or banging objects together, can carry over long distances and alert potential rescuers to your presence.

In contrast, waiting solely for passing aircraft is not an effective strategy since planes may not fly directly over your location and could easily miss you. Staying quiet to avoid drawing attention contradicts the fundamental purpose of signaling for help; making noise or creating visual markers is essential in attracting attention. Lastly, signaling only during the night limits your opportunities for rescue, as daytime visibility can be significantly higher, making it easier for rescuers to detect your signals. Therefore, actively using reflective materials or producing loud sounds maximizes the chances of being seen or heard and increases the likelihood of rescue.
