History
World War I
Established as 91st Aero Squadron in the summer of 1917 at Kelly Field, near San Antonio, Texas, the unit was sent to France during World War I as one of the initial American Expeditionary Force aero squadrons. The 91st served on the Western Front in France as an observation squadron with the French Eighth Army and United States First Army, 3 June – 10 November 1918. The primary mission of the 91st Squadron was to gather information and immediately return to base to report it. After the November 1918 Armistice with Germany, the 91st Aero Squadron remained in Europe, as part of the occupation forces in Germany with the Third Army (United States) until April 1919.

After returning to the United States, the squadron was reorganized and assigned to Rockwell Field, near San Diego in September 1919. In California, its duties consisted of patrolling the southwestern U.S./Mexican border between California and Arizona, performing forest fire patrols and flying training flights over forested areas along the coast of California while assigned to Crissy Field, near San Francisco. Between 1919 and 1922 the squadron frequently moved between bases in California and Oregon with detachments deployed locally to meet operational needs.

Why this record matters
The subject matters to the general reference register because the source frames it as united States Air Force unit. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 9, 2025. The linked authority identifier is Q4645754. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1917, 1918, 1919 and 1922.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
