In 1919, Lieutenant Bănciulescu stood first to fly a Nieuport and on 12 September 1926 with the rank of captain, together with mechanic Ion Stoica aboard a Potez 25, provided by the Franco-Romanian Air Navigation Company, the two took off from Le Bourget airport towards Bucharest to achieve a speed record.

After agonizing days and nights spent in hospitals in Czechoslovakia, Romania and Germany, and after great effort to get used to wearing leg prosthesis, helped by the commander George Negrescu, and his friend Michael Pantazi, his desire to fly again was accomplished.

This happened in July 1927, and in October the same year, Louis Barthou, the French President, gave him the Order of the Legion of Honour in the rank of Chevalier (Knight).

Last raid "to stick Commander" was part of the French civil aviation missions to identify and set air routes over the African continent.

To carry out these missions, George Valentin Bibescu proposed Bănciulescu together with an experienced team, a telegraphist and the driver, which received the French modern aircraft, a Potez 9 AB with two engines.

The second pilot was Douglas Bader, the British RAF wing commander in the Second World War, followed by the Russians Zakhar Sorokin and Alexey Maresyev.
