Thailand Royal Siamese Air Force Biplane Pilots Real Photo Postcard

The biplane pictured is Thiphayanet 1 (ทิพยเนตร ๑), one of the earliest aircraft acquired by the Royal Siamese Aeronautical Service. Identified by the Thai script on its fuselage, this likely French-manufactured Breguet 14 was a pivotal addition to Siam's nascent air force, received around 1918 following World War I. The individuals in flight gear and uniform underscore the military context of this early aviation scene.
