The island is very small with no human inhabitants...Bummer! What would be the best type of emergency signal to alert passing aircraft.
Answer All of the above.
Drawing the letters SOS in beach sand is extremely effective and works all day long. Starting and maintaining 3 fires requires a lot of resources and energy. Only once you actually see an aircraft should you light signal fires or shoot off a flare.
