21 November 1913

On November 21, 1913 , the Caudron brothers organized an airshow at Issy-les-Moulineaux and invited the press to observe the acrobatics of pilot Pierre Chanteloup. Thus, this date is the "official" occasion of the first loop of a biplane in France. In fact, Chanteloup had looped the Caudron biplane earlier (on the 9th) but without witnesses.
