But back to the signal mirror topic ...
A few years ago I was talking to a CA coast guard pilot (helicopter) and asking him what method for emergency signalling was best ... flares, bright color markings, signal mirrors etc. His reply was that on a day with good weather (direct sunlight) the signal mirror was by far the most effective way of attracting help from aircraft - it could easily been seen from over 20 miles away.
