Aeroplanes To Fly Unseen.

New York Times 100 years ago today, January 26, 1913:
Material Discovered by Which They Can Be Made Invisible to Enemy.
    WASHINGTON, Jan. 25.— Invisible aeroplanes will soon be in use in the War Department as the result of discoveries made by officers of the Signal Corps.
    The "invisible" material is liquid, and is molded into shape, but it is said to be lighter and stronger than canvas, and to be adaptable to any description of frame. The War Department expects soon to make public the discovery.
    The great advantage of the invisible aeroplane in time of war is regarded by army officers as incalculable. With the use of the new material they believe that a heavier than air machine would be indistinguishable at a distance of 500 feet, a much nearer flight to an enemy's position than any aviator probably would essay under present conditions.
