Paris–Le Bourget Airport
Undaunted, the men decided to make a second attempt, departing Paris–Le Bourget Airport on 11 September 1931 in a second Dewoitine D.33 named "Trait d'Union II", hoping to beat their competitors, Paul Codos and Henri Robida, who took off the same day in the Breguet 19 TF Super Bidon "Point d'Interrogation" also intending to fly nonstop to Tokyo; Codos and Robida, however, were forced to land at Düsseldorf, Germany, after only a few hours. Flying on, Le Brix, Doret, and Mesmin were over Ufa in the Soviet Union on 12 September when the aircraft's engine failed and they decided to bail out. Doret jumped first, parachuting to safety. Mesmin apparently had trouble with his parachute and could not follow, so Le Brix stayed with the airplane rather than leave Mesmin alone on board. The D.33 crashed and caught fire, killing both Le Brix and Mesmin.
