In the USSR, the names of ace heroes such as Kozhedub, Pokryshkin, Maresyev, and Rechkalov were widely known. However, Russian pilots who fought in the Allied Air Forces were hardly mentioned. One of these heroes was Konstantin Vladimirovich Rozanov, a legend of French aviation. The son of white émigrés, he graduated from the Military School at the age of 28 and worked as a test pilot. World War II found him in this position. Rozanov's first assignment was a responsible one: to ferry a captured Messerschmitt. But he did not want to remain a test pilot and submitted a request to transfer to a fighter unit.

In May 1940, when German troops were advancing on France, Konstantin Vladimirovich demonstrated courage and skill in complex maneuvers. Already that month, he shot down two enemy aircraft. However, the fighting in Europe did not last long, and after France's defeat, Rozanov and his squadron were transferred to North Africa, where he fought as part of the British forces. He also participated in convoy operations off the Mediterranean coast. Over the years of the war, Rozanov became one of the best aces in France, which led to his being sent for retraining in Britain.

At that time, the Allies were developing their first jet aircraft, and Rozanov, as the most experienced pilot, was chosen for their testing. He became one of the first in the world to take to the skies in a jet fighter and later tested American planes. After the war, he headed an airbase on the Atlantic coast of France near Mont-de-Marsan. Unfortunately, in 1954, Rozanov died while testing a new aircraft. In his honor, the Mont-de-Marsan base and one of the streets in Paris were named after him.
