The first solo aviator to make a nonstop transatlantic flight was not French but American—Charles Lindbergh. On May 20–21, 1927, Lindbergh flew solo nonstop from New York to Paris in his aircraft, the Spirit of St. Louis. This historic flight covered about 3,600 miles and took approximately 33.5 hours, making it the first solo nonstop transatlantic flight ever completed

. Regarding French aviators, Louis Blériot was a pioneering French aviator famous for being the first to fly across the English Channel in 1909, but this was not a transatlantic flight

. Two French aviators, Charles Nungesser and François Coli, attempted a transatlantic flight from Paris to New York shortly before Lindbergh but disappeared and were never confirmed to have completed the journey

. In summary:

• The first solo nonstop transatlantic flight was made by American Charles Lindbergh in 1927.
• French aviators like Louis Blériot were pioneers in early aviation but not for the first solo transatlantic flight.
• French aviators Nungesser and Coli attempted the crossing before Lindbergh but did not complete it successfully.
