The emergency signaling mirror is used to attract attention of passing groups?

• A. Aircraft
• B. Boats
• C. Aircraft or boats
• D. Aircraft, land personnel, or boats

Answer: (D)

An emergency signaling mirror is a simple, portable way to catch attention by reflecting sunlight into bright flashes. Because rescuers can come from multiple directions, you want a signal that can be seen from air, sea, or land. That’s why the best answer includes aircraft, land personnel, or boats—signals from the sky, on the water, or on shore can all help alert would-be rescuers. Limiting the signal to just aircraft or just boats could miss observers on the other domains, reducing the chance of being noticed.
