The book "The Four Reigns of Charki Dynasty: The Centennial of the Royal Thai Air Force Founding Fathers' Aviation" explores the evolution of aviation in Thailand, tracing its origins from the early 20th century to the present. Following the Wright Brothers' historic flight in 1903, Thailand's engagement with aviation began in 1911 with an airshow, which sparked national interest in developing its own aviation capabilities. The pivotal moment came on July 2, 1912, when Phraya Chalermakas and Phraya Vehassayarnsilpsit started their flying training in France, marking the beginning of Thai aviation. This milestone is celebrated as a century of aviation progress in Thailand. The book highlights how the Thai aviation pioneers not only established a robust military aviation framework but also contributed to advancements in transportation and commerce, positioning Thailand as a leader in the early development of aviation in Asia.
