Makes Aeroplanes Stable.

New York Times 100 years ago today, August 29, 1912:
Great Things Claimed for the Invention of a Belgian Engineer.
    BRUSSELS, Aug. 28.— A mechanical appliance which will render aeroplanes so stable that they cannot upset, turn turtle, or plunge to the ground while flying has, it is said, been invented by a Belgian engineer.
    It consists of rotary wings which, when put in motion, permit the flying machine to rise directly from the ground, turn in all directions, and plane with perfect security at any height in the air.
    Both progression and ascension, the inventor asserts, can be effected by the apparatus without any backward or forward motion of the wings. He promises fuller details in the near future.
