The history of aviation in Romania began with Conrad Hass, who wrote about the construction and flight tests of multistage rockets. Alexandro Ciurcu and Just Buisson suggested equipping a dirigible with a jet engine in 1886. Traian Vuia performed the first flight of a heavier-than-air aircraft in 1906. Henri Coanda constructed the first jet aircraft in the world, named the Coanda-1910, in 1910. Rodrig Golieseu built and flew his 'Avioplan' in 1909.
