The 94th and 95th Aero Squadrons had trained and traveled together since their organization on 20 August 1917 at Kelly Field, Texas. When the two squadrons boarded a train at Kelly Field on 20 September 1917 for the trip to Mineola, New York, they consisted entirely of the enlisted echelon that would form the squadron's ground support element. Arriving at Mineola on 5 October, the squadrons reported directly to Aviation Mobilization Camp No. 2. Each unit completed training there in about three weeks and proceeded to Pier No. 45, Hoboken, New Jersey where, on 27 October 1917, it boarded the Cunard liner RMS Carpathia for the trip to Europe.
