French-German Air Treaty.

New York Times 100 years ago today, August 14, 1913:
Aircraft Across Frontier Driven by Bad Weather to Descend.
By Marconi Transatlantic Wireless Telegraph to The New York Times.
    PARIS, Aug. 13.— A convention has been signed between France and Germany providing for the future landings of aircraft in each other's territory such as the descent of a German Zeppelin airship at Luneville last April.
    In case military aircraft, French or German, are driven by stress of weather over the territory of the neighboring country their pilots are to hoist signals of distress and to descend as soon as possible.
    The commander of a trespassing airship will be called upon to pledge his word of honor that nobody in the airship has committed any act, such as sketching or photographing, capable of affecting the security of the country in which he landed.
