On 6 February 1928, Lieutenant Dieudonné Costes and Lieutenant Commander Joseph Lebrix landed at Boiling Field, Washington, D.C., in the plane which had carried them from Paris across the South Atlantic and over South America to Mexico and the United States. In 1930 Costes and Maurice Bellonte made the first Paris to New York flight. The following year Costes was named the world's No. 1 airman by the International League of Aviation. In 1949 a French military court acquitted Costes on charges of spying for the Nazis during World War II. Needing six votes for a conviction under French military law, four judges voted to convict while five judges voted to free Costes.
