Aeroplane Finds Submarine.

New York Times 100 years ago today, December 27, 1912:
Signal Corps Says Airmen Can Detect Under-Water Operations.
    WASHINGTON, Dec. 26.— The Navy Department is bowing to the Signal Corps, which has announced that aeroplanes can be used for the purpose of discovering the whereabouts and movements of submarines. It is said that experiments at Annapolis have developed the fact that the operators in the air craft can discover the presence of the under-water terrors without glasses, although they may be at a considerable depth.
    This, in the opinion of naval officers, may advance the plan of having aeroplanes as a part of the equipment of all the fighting craft in the United States Navy.
