X-Plane 11.50+ Breguet XIV "Lignes Aeriennes Latecoere" 1.0. The Breguet XIV (in contemporary practice) or Breguet 14 was a French biplane bomber and reconnaissance aircraft of World War I. It was built in very large numbers and production continued for many years after the end of the war. The 14 Tbis also formed the basis of the improved 14 Tbis Sanitaire air ambulance version, and 100 mail planes custom-built for Latecoere's airline, Lignes Aeriennes Latecoere. Credit goes to Beber for the use of his pilot. By Philippe Gastebois.
