One Unwelcome Way of Greeting Enemy Aeroplanes

���To guard the shores of Long Island, New York, against aerial attacks the Government has installed a five hundred million-candle- power searchlight on the aviation field at Hempstead. The light is to be used in co- operation with anti-aircraft guns, to locate and destroy any invading enemy craft

��To test the searchlight, aviators will go up in biplanes, followed by "enemy" craft. The huge light will "find" the enemy, after which our aviators will emerge from the darkness and give chase. If any of the enemy escape, our men are supposed to follow them beyond the searchlight radius until they are captured
