This barograph provided an accurate record of the altitude and flight duration of "The Spirit of St. Louis" as Charles Lindbergh flew it nonstop from New York to Paris on May 20, 1927. Lindbergh needed a barograph tracing of his flight because he was competing for a $25,000 prize offered by New York hotel owner Raymond Orteig for the completion of the first nonstop flight between New York and Paris. The regulations of the Fédération Aéronautique Internationale required a barograph tracing of all competitive flights to ensure that a nonstop flight was truly nonstop.
Recorded on the drum were Lindbergh's takeoff and climb, his ascents to various altitudes in search of favorable winds, his attempts to rise over storms and fog banks, his sudden drops because of turbulent air, his partial descent near Ireland, his flight over southwest Britain and northwest France, and finally his landing in Paris.
