On November 1, 1915, Captain Raynal Cawthorne Bolling—a prominent New York attorney working at United States Steel—organized the Aviation Detachment, 1st Battalion Signal Corps of the New York National Guard (now the 102d Rescue Squadron). It was the Guard's first genuine aviation unit. Subsequently, the organization was redesignated the 1st Aero Company. Located at Mineola on Long Island, the unit rented and then purchased its own aircraft with funds donated by the Aero Club of America and other contributors. It was "provisionally recognized" on June 22, 1916, and then called into federal service on July 13, 1916, during the Mexican border crisis. However, instead of active service in the southwest, it remained at Mineola training and was released from federal service on November 2, 1916.
