Spirit of St. Louis at Kearney Mesa, San Diego, California. (Donald A. Hall)

Following its first flight from Dutch Flats on 28 April 1927, Charles A. Lindbergh continued flight testing of the new Ryan NYP, N-X-211, Spirit of St. Louis, over the following week from the Camp Kearney parade grounds (now known as Kearney Mesa) near San Diego, California.

Data was gathered for takeoff and landing distances, obstacle clearance, power settings, fuel consumption, rates of climb, air speeds, speeds over a measured distance, instrument calibrations. . . All the things that need to be known so that reliable planning for a transcontinental and transoceanic flight could be carried out.

In his book, The Spirit of St. Louis, (Charles Scribner’s and Sons, 1953) Lindbergh wrote about having a gust of wind blow his clipboard containing the carefully collected data out the Spirit‘s window, and his efforts to recover it, which he did.

This photograph of the legendary airplane flying at Camp Kearney was taken by Donald A. Hall, the engineer who designed it.
