Chailly-en-Brie Aerodrome

Chailly-en-Brie Aerodrome was a temporary World War I airfield in France. It was located 1 mi South of Chailly-en-Brie, in the Seine-et-Marne department in the Île-de-France region in north-central France.

Overview
The airfield was a temporary facility, likely consisting of no more than a few tents that was established by the I Corps Observation Group during the Aisne-Marne Offensive Campaign during the end of August 1918. Two of the group's squadrons, the 1st and 12th Aero Squadrons operated from the field for a few days until moving to Gengault Aerodrome, near Toul.

After the brief use by the Americans, it was turned over to the French and it's subsequent history is undermined. After the armistice, the airfield was returned to agricultural use. Today it is a series of cultivated fields located south of Chailly-en-Brie. The airfield was located to the east of the Départmental 209 (D209), with no indications of its wartime use.
