The Royal Aeronautical Society is formed in London.

The Royal Aeronautical Society (RAeS) is one of the world’s oldest and most respected professional institutions dedicated to aerospace. Founded in 1866 in the United Kingdom, it was established at a time when human flight was still largely theoretical, making its early role especially influential in shaping aeronautical thought. From the outset, the Society aimed to advance the art, science, and engineering of aeronautics, bringing together pioneers, engineers, scientists, and enthusiasts to exchange ideas and promote innovation in flight.

Over time, the Royal Aeronautical Society has evolved into a global authority covering all aspects of aerospace, including civil and military aviation, space, rotorcraft, unmanned systems, and emerging technologies. It plays a central role in professional accreditation, offering membership grades and professional registration such as Chartered Engineer status. Through conferences, lectures, specialist groups, and technical publications, the Society provides a platform for sharing cutting-edge research, operational experience, and policy insights across the international aerospace community.

Beyond its technical and professional functions, the RAeS also serves as a steward of aerospace heritage and education. Its extensive historical archives and National Aerospace Library preserve key documents, images, and records that chart the development of flight from early experiments to modern space exploration. At the same time, the Society actively supports future generations through scholarships, outreach programs, and career resources, reinforcing its long-standing mission to inspire excellence and leadership in aerospace worldwide.
