After a flight of 33 hours, 30 minutes, 30 seconds, from Roosevelt Field, Long Island, New York, United States of America, Charles A. Lindbergh lands his Spirit of St. Louis at Le Bourget Aerodrome, Paris, France, at 10:22 p.m. (20:22 G.M.T.), 21 May 1927. He is the first pilot to fly solo, non-stop, across the Atlantic Ocean.

“I circle. Yes, it’s definitely an airport. . . It must be Le Bourget. . . I shift fuel valves to the center wing-tank, sweep my flashlight over the instrument board in a final check, fasten my safety belt, and nose the Spirit of St. Louis down into a gradually descending spiral. . .

“I straighten out my wings and let the throttled engine drag me on beyond the leeward border. Now the steep bank into the wind, and the dive toward the ground. But how strange it is, this descent. I’m wide awake, but the feel of my plane has not returned. . . My movements are mechanical, uncoordinated, as though I were coming down at the end of my first solo. . .

“It’s only a hundred yards to the hangars now — solid forms emerging from the night. I’m too high — too fast. Drop wing — left rudder — sideslip — — — Careful — mustn’t get anywhere near the stall — — — I’ve never landed the Spirit of St. Louis at night before. . . Below the hangar roofs now — — — straighten out — — — A short burst of the engine — — — Over the lighted area — — — Sod coming up to meet me. . . Still too fast — — — Tail too high — — — The wheels touch gently — off again — No, I’ll keep contact — Ease the stick forward — — — Back on the ground — Off — Back — the tail skid too — — — Not a bad landing. . . .”

The Spirit of St. Louis, by Charles A. Lindbergh, Charles Scribner’s Sons, 1953, Pages 489–492.

Lindbergh established a Fédération Aéronautique Internationale (FAI) World Record for Distance in a Straight Line Without Landing of 5,809 kilometers (3,310 miles). ¹

Over 100,000 people have come to Le Bourget to greet Lindbergh. He has flown the Spirit of St. Louis into history.

On 25 February 1927, Charles A. Lindbergh, backed by a group of St. Louis, Missouri, businessmen, contracted the Ryan Airlines Company to build an airplane for the purpose of flying across the Atlantic Ocean from New York to Paris. The agreed price was $10,580. 63 days later, 28 April, Lindbergh made the first flight of the Ryan NYP at Dutch Flats, a short distance from the factory on Juniper Street.

The Ryan NYP is a single-place, single-engine, strut-braced high-wing monoplane with fixed landing gear and tail skid, built at the Ryan Airlines Company factory, San Diego, California. Although it was based on the earlier Ryan M-2, Spirit of St. Louis was a complete redesign, with longer wings and fuselage. The ailerons are smaller. The airplane has no serial number and was not issued a type certificate by the Civil Aeronautics Authority. It was assigned an experimental registration number, NX211.

Spirit of St. Louis is 27 feet, 8 inches (8.433 meters) long with a wingspan of 46 feet, 0 inches (14.021 meters) and height of 9 feet, 10 inches (2.997 meters). The wing has a chord of 7 feet, 0 inches (2.134 meters) and area of 319 square feet (29.636 square meters). There is no dihedral or sweep. The airfoil is the Clark Y, with a cambered upper surface, while the lower surface is flat from aft of the wing’s forward spar.

The fuselage and tail surfaces are constructed of welded tubular SAE 1020 steel framework covered with doped linen fabric. The wing was built as a single unit with wooden spars and ribs. The leading edge is covered in plywood and the entire wing with doped fabric. The rib spacing is 11 inches (27.94 centimeters). The horizontal stabilizer is adjustable from the cockpit to control trim as the fuel load decreased.

The split-axle main landing gear uses bungee cords for shock absorption. B.F. Goodrich pneumatic tires are mounted on 21 inch × 4 inch (533 millimeter × 102 millimeter) wire-spoked wheels. The struts were designed for a load factor of 4 and allow 6½ inches (165 millimeters) of vertical motion. The wheels can spread to absorb impacts. The tail skid is heat-treated chrome moly tubing.

The main fuel tank and lubricating oil tank were placed in front of the cockpit for safety reasons, but this eliminated any forward view for the pilot. A small retractable periscope with a 3 inch × 5 inch (76 × 127 millimeters) viewing area in the instrument panel could be extended through the left side of the fuselage.

Spirit of St. Louis was powered by an air-cooled, normally-aspirated 787.26-cubic-inch-displacement (12.901 liter) Wright Aeronautical Corporation Model J-5C Whirlwind nine-cylinder radial engine, serial number 7331. This was a direct-drive engine with a compression ratio of 5.1:1. The engine was assembled by Thomas W. Rutledge at the Wright factory in Paterson, New Jersey, and was completed 1 April 1927.

The J-5 was built with a cylindrical cast aluminum crankcase and steel cylinder barrels with integral cooling fins. The cylinder head was cast aluminum with a hemispherical combustion chamber, which allowed larger valves and improved combustion efficiency. There were two valves per cylinder, actuated by pushrods and rocker arms.

The Wright J-5C was rated at 200 horsepower at 1,800 r.p.m., and 220 horsepower at 2,000 r.p.m. The engine was 2 feet, 10 inches (0.864 meters) long and 3 feet, 9 inches (1.143 meters) in diameter. It weighed 508 pounds (230.4 kilograms).

During 50-hour endurance tests, the J-5C produced 216 horsepower at 1,837 r.p.m., and 238 horsepower at 1,970 r.p.m. It averaged 223 horsepower during a 100-hour, full-throttle test conducted by the U.S. Navy in May 1927. An overload test run with an external supercharger produced 295 horsepower at 2,150 r.p.m. for 50 hours.

The engine drove a two-bladed Standard Steel Propeller Co. adjustable-pitch propeller with a diameter of 8 feet, 9 inches (2.667 meters). The drop-forged solid Duralumin blades attached to a steel hub. The pitch of the propeller blades could be set prior to flight. Spirit of St. Louis‘ blades were set to 16¼ inches (41.275 centimeters). (This is the distance that the propeller would travel forward during one revolution.)

During flight testing at San Diego, the maximum speed of Spirit of St. Louis was found to be 120.0 miles per hour (193.1 kilometers per hour) at full load, increasing to 124.5 miles per hour (200.4 kilometers per hour) when lightly loaded. It reached 129 miles per hour (207.6 kilometers per hour) over a 3-kilometer course, when the fuel load was just 25 gallons (95 liters). The Ryan’s best economic speed was 97 miles per hour (156.1 kilometers per hour) at full load, and 67 miles per hour (107.8 kilometers per hour), light. Under ideal conditions, the airplane had a maximum range of 4,110 miles (6,614 kilometers).

Spirit if St. Louis has an empty weight of 2,150 pounds (975 kilograms). When in departed San Diego on 10 May 1927, it was overloaded with an additional 25 gallons (94.6 liters) of gasoline, bringing the total gross weight at takeoff to 5,250 pounds (2,381 kilograms). (The density of California gasoline was 6.12 pounds per gallon/0.73 kilograms per litre.)

Designer Donald A. Hall estimated that the Ryan NYP required 850 engineering man hours and 3,000 construction man hours.

Spirit of St. Louis made 174 flights, with a total duration of 489 hours, 28 minutes. NX211 last made its final flight 30 April 1928, from St. Louis, Missouri, to Bolling Field, Washington, D.C., where Charles A. Lindbergh presented it to the Smithsonian Institution. Its registration was cancelled 2 June 1928.

20 May 1927, 7:51:30 a.m. Eastern Daylight Time (11:51:30 G.M.T.): In his effort to advance the Art and Science of Aviation, to win the $25,000 Orteig Prize, to fly from New York to Paris, 25-year-old aviator Charles A. Lindbergh takes off from Roosevelt Field, Long Island, New York, United States of America, and heads north-eastward over the Atlantic Ocean on his solo, record-breaking flight to Paris, France, and into History.

As he circles to gain altitude after takeoff, Lindbergh scans his instruments.

“On the instrument board in front of me, the earth-inductor compass needle leans steeply to the right. I bank cautiously northward until it rises to the center line — 65 degrees — the compass heading for the first 100-mile segment of my great-circle route to France and Paris. It’s 7:54 a.m. Eastern daylight time.”

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.

“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.”
