11 May 1927: At 8:20 a.m., Central time, Charles A. Lindbergh and the Spirit of St. Louis touched down at Lambert Field, St. Louis, Missouri, and taxied to the National Guard hangars where he shut down the Wright J-5C Whirlwind engine. The overnight flight from Rockwell Field on North Island, San Diego, California, took 14 hours, 25 minutes, a new speed record.
It is just eighty days since Lindbergh left St. Louis by train to meet with Ryan Airlines Company to discuss designing and building an airplane that would become the Ryan NYP, N-X-211, the Spirit of St. Louis.
Though the members of the syndicate that is funding his New York-to-Paris flight have planned celebrations, Lindbergh is anxious to continue on to New York City.
10 May 1927: At 3:55 p.m., PST, Charles A. Lindbergh and his Spirit of St. Louis lifted off from Rockwell Field on North Island, San Diego, California, for their record-setting overnight flight to St. Louis, Missouri. The new Ryan NYP, N-X-211, had been ready and all the flight tests complete since 4 May. Lindbergh had completed the navigational planning for both the transcontinental flight to New York City, and then, the transoceanic flight to Paris. He had been in daily consultation with Dean Blake, chief of the Weather Bureau in San Diego. A system over the Rockies had been holding up his departure for days, but now everything was ready. Lindbergh wrote:
At 3:40 I crawl into my flying suit. It’s uncomfortably hot in the California sun. . . It’s a few minutes early, but why wait any longer in this heat? I wave good-by, taxi into position, and ease the throttle open. As I pick up speed, I hold the tail low to put as much load as possible on the wings and reduce strain on the landing gear.
The Spirit of St. Louis is in the air soon after its wheels start clattering over the hummocky portion of the field. The take-off wasn’t as difficult as I expected. It’s 3:55 Pacific. I make a mental note of the time, check instruments, pull the throttle back slightly, and begin a wide climbing turn to the left. Two army observation planes and a Ryan monoplane have taken off with me as an escort. Colonel Graham, the Commanding Officer at Rockwell Field, is in one of the observation planes. Hall, Bowlus, Harrigan, and A.J. Edwards are in the Ryan. We circle North Island, the factory, and the city of San Diego. Then, leaving the ocean and the bay behind, I set my compass heading for St. Louis.

4 May 1927: Charles A. Lindbergh completes his last series of flight tests of the Ryan NYP, N-X-211, Spirit of St. Louis. Flying at 50 feet (15.2 meters) over San Diego Bay, he times the Spirit‘s flight from marker to marker with a stop watch. The airspeed indicator jumps past 130 miles per hour (209.2 kilometers per hour). He records indicated air speed and engine r.p.m. at various power settings. At 1,500 r.p.m. the Spirit can fly at 96 miles per hour (154.5 kilometers per hour). He makes three runs in each direction to come up with averages.
After the speed runs, Lindbergh flies back to Camp Kearney for load tests. Take-off distances are measured while increasing the fuel load in 50 gallon (189.3 liter) increments.
“Twilight is thickening. We stake the Spirit of St. Louis down and leave it under guard. . . When I get back to the city, I telegraph my partners that the tests are satisfactorily completed. . . .”
