43 flying training, air park (supply), depot (maintenance), and construction squadrons were located in the Services of Supply. A major air depot at Colombey-les-Belles; three other maintenance depots at Behonne, LaTrecey, and Vinets; four supply depots at Clichy, Romorantin, Tours, and Is-sur-Tille; and 12 air park squadrons maintained the combat and training forces. Aircraft acquired from European sources were accepted at Aircraft Acceptance Park No. 1 at Orly, while those shipped from the United States for assembly in France were delivered to Air Service Production Center No. 2, built on the site of a former pine forest at Romorantin. Ferry operations of over 6,300 new aircraft to the air depots in "often...far from perfect" weather conditions resulted in the successful delivery of 95% and the loss of only eight pilots.
