Robertson Aircraft Corporation was a post- World War I American aviation service company based at the Lambert-St. Louis Flying Field near St. Louis, Missouri, that flew passengers and U.S. Air Mail , gave flying lessons, and performed exhibition flights. It also modified, re-manufactured, and resold surplus military aircraft including Standard J , Curtiss Jenny/Canuck , DeHavilland DH-4 , Curtiss Oriole , Spad , Waco , and Travel Air types in addition to Curtiss OX-5 engines.
82-713: The Spirit of St. Louis (formally the Ryan NYP , registration: N-X-211) is the custom-built, single-engine, single-seat, high-wing monoplane that Charles Lindbergh flew on May 20–21, 1927, on the first solo nonstop transatlantic flight from Long Island, New York , to Paris, France , for which Lindbergh won the $ 25,000 Orteig Prize . Lindbergh took off in the Spirit from Roosevelt Airfield in Garden City, New York , and landed 33 hours, 30 minutes later at Aéroport Le Bourget in Paris,

Although the first successful aircraft were biplanes, the first attempts at heavier-than-air flying machines were monoplanes, and many pioneers continued to develop monoplane designs. For example, the first aeroplane to be put into production
246-427: A negatively stable design that tended to randomly introduce unanticipated pitch , yaw , and bank (roll) elements into its overall flight characteristics. There is a dispute regarding whether Hall and Lindbergh also preferred this design because they anticipated that the continuous corrections to the random movements of the aircraft would help to keep Lindbergh awake during the estimated 40-hour flight. Whether or not

In the aftermath of the media exposure surrounding Lindbergh's transatlantic flight, he flew to Washington with his wife on board to greet the triumphant Lindbergh. Due to the ensuing publicity, Hawks was hired by

Monoplane A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes , which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during

Lindbergh subsequently flew the Spirit of St. Louis to Belgium and England before President Calvin Coolidge sent the light cruiser Memphis to bring them back to the United States. Arriving on June 11, Lindbergh and the Spirit were escorted up the Potomac River to Washington, D.C. , by a fleet of warships, multiple flights of military pursuit aircraft, bombers, and the rigid airship Los Angeles (which

The main compass was mounted behind Lindbergh in the cockpit, and he read it using the mirror from a women's makeup case which was mounted to the ceiling using chewing gum. Lindbergh also installed a newly developed Earth Inductor Compass made by the Pioneer Instrument Company which allowed him to more accurately navigate while taking account of the magnetic declination of

#1732852579388984-544: A low-wing, shoulder-wing and high-wing configurations give increased propeller clearance on multi-engined aircraft. On a large aircraft, there is little practical difference between a shoulder wing and a high wing; but on a light aircraft, the configuration is significant because it offers superior visibility to the pilot. On light aircraft, shoulder-wings tend to be mounted further aft than a high wing, and so may need to be swept forward to maintain correct center of gravity . Examples of light aircraft with shoulder wings include
1066-425: A precaution against hitting ship masts, trees, or structures while flying at low altitude, a Ryan employee who had served in the submarine service installed a periscope which Lindbergh helped design. It is unclear whether the periscope was used during the flight. The instrument panel housed fuel pressure, oil pressure and temperature gauges, a clock, altimeter, tachometer, airspeed indicator, bank and turn indicator, and
1148-441: A pylon. Additional bracing may be provided by struts or wires extending from the fuselage sides. The first parasol monoplanes were adaptations of shoulder wing monoplanes, since raising a shoulder mounted wing above the fuselage greatly improved visibility downwards, which was useful for reconnaissance roles, as with the widely used Morane-Saulnier L . The parasol wing allows for an efficient design with good pilot visibility, and
1230-593: A shorter wingspan. Under the newly restructured B.F. Mahoney Company, further development continued with the six-place Model B-7 utilizing a 420 hp (310 kW) engine and the Model C-1 with the basic 220 hp (160 kW) engine. Shortly after the original Spirit was retired in April 1928, the Mahoney Aircraft Corporation presented Lindbergh with a Mahoney Ryan B-1 "Brougham". In 1928, Mahoney built
1312-467: Is a configuration whereby the wing is mounted near the top of the fuselage but not on the very top. It is so called because it sits on the "shoulder" of the fuselage, rather than on the pilot's shoulder. Shoulder-wings and high-wings share some characteristics, namely: they support a pendulous fuselage which requires no wing dihedral for stability; and, by comparison with a low-wing, a shoulder-wing's limited ground effect reduces float on landing. Compared to

Hall of Ryan Airlines and named the "Spirit of St. Louis" in honor of Lindbergh's supporters from
1640-501: Is where the wing is mounted vertically on the fuselage . A low wing is one which is located on or near the bottom of the fuselage. Placing the wing low allows good visibility upwards and frees the central fuselage from the wing spar carry-through. By reducing pendulum stability, it makes the aircraft more manoeuvrable, as on the Spitfire ; but aircraft that value stability over manoeuvrability may then need some dihedral . A feature of
1722-621: The ARV Super2 , the Bölkow Junior , Saab Safari and the Barber Snark . A high wing has its upper surface on or above the top of the fuselage. It shares many advantages and disadvantages with the shoulder wing, but on a light aircraft, the high wing has poorer upwards visibility. On light aircraft such as the Cessna 152 , the wing is usually located above the cabin, so that the wing spar passes over

Through the efforts of both staff and volunteers, the Experimental Aircraft Association in Oshkosh, Wisconsin produced two reproductions of the Spirit of St. Louis , powered by Continental R-670 -4 radial engines, the first in 1977 (of which
2132-507: The Spirit of St. Louis is a golden color because of a well-intentioned but mistaken attempt by us to preserve the markings on the cowling. We don’t know exactly when, but soon after the Smithsonian acquired the Spirit in May 1928, we sought to preserve the markings by applying a clear coat of varnish or shellac. Unfortunately, over the years, this coating has yellowed with age. While it has taken on
2214-431: The Spirit of St. Louis was also one of the most advanced and aerodynamically streamlined designs of its era. Lindbergh believed that a flight made in a single-seat monoplane designed around the dependable Wright J-5 Whirlwind radial engine provided the best chance of success. The Ryan NYP had a total fuel capacity of 450 U.S. gallons (1,700 L; 370 imp gal) or 2,710 pounds (1,230 kg) of gasoline, which

Advanced monoplane fighter-aircraft designs were mass-produced for military services around

The German military Idflieg aircraft designation system prior to 1918 prefixed monoplane type designations with an E , until the approval of the Fokker D.VIII fighter from its former "E.V" designation. However, the success of the Fokker was short-lived, and World War I was dominated by biplanes. Towards the end of the war, the parasol monoplane became popular and successful designs were produced into
2460-405: The 1920s. Nonetheless, relatively few monoplane types were built between 1914 and the late 1920s, compared with the number of biplanes. The reasons for this were primarily practical. With the low engine powers and airspeeds available, the wings of a monoplane needed to be large in order to create enough lift while a biplane could have two smaller wings and so be made smaller and lighter.

Lindbergh was convinced: "I believe in Hall's ability; I like Mahoney's enthusiasm. I have confidence in the character of the workmen I've met." He then went to the airfield to familiarize himself with a Ryan aircraft, either an M-1 or an M-2, then telegraphed his St. Louis backers and recommended

Working exclusively on the aircraft and closely with Lindbergh, the staff completed the Spirit of St. Louis 60 days after Lindbergh arrived in San Diego. Powered by a Wright Whirlwind J-5C 223-hp radial engine, it had a 14 m (46-foot) wingspan, 3 m (10 ft) longer than the M-1, to accommodate the heavy load of 1,610 L (425 gal) of fuel. In his 1927 book We , Lindbergh acknowledged
3362-413: The early 1930s. However, the exposed struts or wires create additional drag, lowering aerodynamic efficiency and reducing the maximum speed. High-speed and long-range designs tend to be pure cantilevers, while low-speed short-range types are often given bracing. Besides the general variations in wing configuration such as tail position and use of bracing, the main distinction between types of monoplane

3444-400: The early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds

3690-471: The end of the First World War, the inherent high drag of the biplane was beginning to restrict performance. Engines were not yet powerful enough to make the heavy cantilever-wing monoplane viable, and the braced parasol wing became popular on fighter aircraft, although few arrived in time to see combat. It remained popular throughout the 1920s. On flying boats with a shallow hull, a parasol wing allows
3772-418: The engine in the event of a crash. This design decision meant that there could be no front windshield, and that forward visibility would be limited to the side windows. This did not concern Lindbergh as he was accustomed to flying in the rear cockpit of mail planes with mail bags in the front. When he wanted to see forward, he would slightly yaw the aircraft and look out the side. To provide some forward vision as

Another key feature of the Whirlwind radial engine was that it was rated to self-lubricate the engine's valves for 40 hours continuously. Lubricating, or "greasing," the moving external engine parts was a necessity most aeronautical engines of the day required, to be done manually by

Lindbergh was reputed to have flown one of the reproductions during the film's production, however, the connection to Lindbergh is now considered a myth. On the 40th anniversary of Lindbergh's flight, a new reproduction named Spirit 2 was built by a movie stunt pilot, Frank Tallman . It first flew on April 24, 1967, and appeared at

Mahoney was away from the factory, but Ryan answered, "Can build plane similar M-1 but larger wings... delivery about three months." Lindbergh wired back that due to competition, delivery in less than three months was essential. Many years later, John Vanderlinde, chief mechanic of Ryan Airlines, recalled, "But nothing fazed B.F.

At Lindbergh's request, the large main and forward fuel tanks were placed in the forward section of the fuselage, in front of the pilot, with the oil tank acting as a firewall. This arrangement improved the center of gravity and reduced the risk of the pilot being crushed to death between the main tank and
4428-427: The low-wing position is its significant ground effect , giving the plane a tendency to float farther before landing. Conversely, this ground effect permits shorter takeoffs. A mid wing is mounted midway up the fuselage. The carry-through spar structure can reduce the useful fuselage volume near its centre of gravity, where space is often in most demand. A shoulder wing (a category between high-wing and mid-wing)

Hall decided that the empennage (tail assembly) and wing control surfaces would not be altered from his original Ryan M-2 design, thus minimizing redesign time that was not available without delaying the flight. The result was less aerodynamic stability; nevertheless, the experienced Lindbergh approved the unaltered design. This setup resulted in

Lindbergh also insisted that unnecessary weight be eliminated, even going so far as to cut
5248-406: The wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost.

5986-469: Was itself a veteran of one of the earliest transatlantic flights), where President Coolidge presented the 25-year-old U.S. Army Reserve aviator with the Distinguished Flying Cross . On the same day, the U.S Post Office issued a commemorative 10-cent "Lindbergh Air Mail" stamp depicting the Spirit over a map of its flight from New York to Paris, and which was also the first stamp issued by
6068-401: Was meant as a message of good luck prior to Lindbergh's solo Atlantic crossing as the symbol was often used as a popular good luck charm with early aviators and others. The inside of the original propeller spinner can be viewed at the National Air and Space Museum . This propeller spinner was found to be cracked when Lindbergh arrived at New York prior to his transatlantic flight. A replacement
6150-434: Was necessary in order to have the range to make the anticipated flight non-stop. The fuel was stored in five fuel tanks, a forward tank – 88 U.S. gal (330 L; 73 imp gal), the main – 209 U.S. gal (790 L; 174 imp gal), and three wing tanks – total of 153 U.S. gal (580 L; 127 imp gal). Lindbergh modified the design of the plane's "trombone struts" attached to
6232-553: Was obtained by Palen in the 1970s for the project's start, with original, and still-functional 1920s-era flight instruments being incorporated — including the same basic type of earth inductor compass used by Lindbergh — matching the ones in the original Spirit at the NASM. This reproduction aircraft successfully flew in early December 2015 in upstate New York, piloted by aircraft restorer/builder Ken Cassens of Stone Ridge, New York . The aircraft made its public debut flight on May 21, 2016,
6314-687: Was owned and operated by brothers Maj. William B. Robertson (1893–1943) and Frank H. Robertson (1898–1938) who were both former US Army aviators. William Robertson left the company in 1928 to form the Curtiss-Robertson division of Curtiss-Wright to produce aircraft such as the Curtiss Robin , which RAC sold. On April 15, 1926, Robertson Aircraft started Contract Air Mail service over route CAM-2 from Lambert Field to Chicago, with stops in Springfield, Illinois and Peoria, Illinois ; Charles Lindbergh
6396-479: Was providing daily passenger and express service as well over the St. Louis - Chicago mail route flown in 12-passenger Stout Ford Tri-Motors . During the Great Depression Robertson's flight operations were merged into Universal Aviation Corporation along with Continental Airlines , Northern Air Lines, and Paul R. Braniff Inc., which became Braniff International Airways Universal Aviation became
6478-473: Was registered as J-BACC and achieved a number of record-breaking flights early in 1928 before a crash ended its career. Although Ryan capitalized on the notoriety of the NYP special, further developments were only superficially comparable to the Spirit of St. Louis . An offshoot of the Ryan B-1 Brougham emerged as a five-seater with the same J-5 engine but modified with a conventional cockpit layout and
6560-540: Was the 1907 Santos-Dumont Demoiselle , while the Blériot XI flew across the English Channel in 1909. Throughout 1909–1910, Hubert Latham set multiple altitude records in his Antoinette IV monoplane, eventually reaching 1,384 m (4,541 ft). The equivalent German language term is Eindecker , as in the mid-wing Fokker Eindecker fighter of 1915 which for a time dominated the skies in what became known as
6642-610: Was to be based on a conversion from a B-1 Brougham; the aircraft proved to be too badly deteriorated to be used in that manner), flown by EAA founder Paul Poberezny to commemorate the 50th anniversary of Lindbergh's flight across the Atlantic Ocean and subsequent tour of the United States. This example is now on display in the main museum gallery. A second reproduction, started from scratch in 1977 and first flown in November 1990, continues to fly at air shows and commemorative events. Both of
6724-872: Was written off on May 31, 2003. Shortly after takeoff at an air show in Coventry, England, structural failure occurred, resulting in a fatal crash, killing its owner-pilot, Captain Pierre Holländer. A recently completed Spirit reproduction, intended for airworthiness is owned by the Old Rhinebeck Aerodrome (ORA), fulfilling a lifelong dream of its primary founder, Cole Palen (1925–1993). The reproduction project had been started by Cole before his own death and has mostly been subsequently built by former ORA pilot and current vintage aircraft maintenance manager Ken Cassens, receiving its wing covering, completed with doped fabric in 2015.
