Major Rudolph William Schroeder, Air Service, United States Army

27 February 1920: Major Rudolph William Schroeder, Chief Test Pilot of the Engineering Division, McCook Field, Ohio, flew a Packard Lepère L USA C.II biplane to a Fédération Aéronautique Internationale (FAI) World Record Altitude of 10,093 meters (33,114 feet).¹ The biplane was powered by a turbosupercharged Liberty L-12 aircraft engine producing 443 horsepower.

There are differing accounts of what occurred during the flight. One report is that the L USA C.II created the very first contrail as it flew at altitudes and temperatures never before reached. Also, there are differences in explanations of some type of problem with Major Schroeder’s oxygen supply. A valve may have frozen, the regulator did not operate correctly, or one of his tanks was empty. Another source says that he ran out of fuel. But he apparently suffered hypoxia and began to lose consciousness. He may have lost control, or intentionally dived for lower altitude. The airplane dived nearly 30,000 feet (9,144 meters) before Schroeder pulled out and safely landed. He was in immediate need of medical attention, however.

Recording instruments indicated that he had been exposed to a temperature of -67 °F. (-55 °C.). His goggles had iced over, and when he raised them, his eyes were injured by the severe cold.

Schroeder’s barograph recorded a peak altitude of 37,000 feet (11,277.6 meters). When the device was calibrated after landing, it indicated that his actual maximum altitude was 36,020 feet (10,979 meters).

The Fédération Aéronautique Internationale (FAI) delegated responsibility for certifying the record to the Aero Club of America, whose representatives apparently felt that procedures for setting the record had not been correctly followed, and declined to accept the altitude record.

The National Bureau of Standards next evaluated the data and credited Rudolph Schroeder with having reached 33,180 feet (10,113 meters). Regardless, the current official record altitude, according to FAI, remains 10,093 meters (33,114 feet).

The Packard Lepère L USA C.II was a single-engine, two-place biplane fighter which was designed by the French aeronautical engineer, Capitaine Georges Lepère, who had previously designed the Section Technique de l’Aeronautique Dorand AR.1 reconnaissance airplane for France’s military air service. The new airplane was built in the United States by the Packard Motor Car Company of Detroit, Michigan. It was a two-place fighter, or chasseur, light bomber, and observation aircraft, and was armed with four machine guns.

The L USA C.II was 25 feet, 3-1/8 inches (7.699 meters) long. The upper and lower wings had an equal span of 41 feet, 7¼ inches (12.681 meters), and equal chord of 5 feet, 5¾ inches (1.670 meters). The vertical gap between the wings was 5 feet, 1/8-inch (1.527 meters) and the lower wing was staggered 2 feet, 15/16-inch (0.633 meters) behind the upper wing. The wings’ incidence was +1°. Upper and lower wings were equipped with ailerons, and had no sweep or dihedral. The height of the Packard Lepère, sitting on its landing gear, was 9 feet, 7 inches (2.921 meters).

The fuselage was a wooden structure with a rectangular cross section. It was covered with three layers of veneer, (2 mahogany, 1 white wood) with a total thickness of 3/32-inch (2.38 millimeters). The fuselage had a maximum width of 2 feet, 10 inches (0.864 meters) and maximum depth of 4 feet, 0 inches (1.219 meters).

The wings were also of wooden construction, with two spruce spars and spruce ribs. Three layers of wood veneer covered the upper surfaces.

The Packard Lepère had an empty weight of 2,561.5 pounds (1,161.9 kilograms) and its gross weight was 3,746.0 pounds (1,699.2 kilograms).

The Packard Lepère was powered by a water-cooled, normally-aspirated, 1,649.34-cubic-inch-displacement (27.028 liter) Packard-built Liberty 12 single overhead cam (SOHC) 45° V-12 engine, which produced 408 horsepower at 1,800 r.p.m., and drove a two-bladed, fixed-pitch propeller with a diameter of 9 feet, 10 inches (2.997 meters). The Liberty 12 was 5 feet, 7.375 inches (1.711 meters) long, 2 feet, 3.0 inches (0.686 meters) wide, and 3 feet, 5.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).

The engine coolant radiator was positioned horizontally in the center section of the airplane’s upper wing. Water flowed through the radiator at a rate of 80 gallons (303 liters) per minute.

The L USA C.II had a maximum speed of 130.4 miles per hour (209.9 kilometers per hour) at 5,000 feet (1,524 meters), 127.6 miles per hour (205.4 kilometers per hour) at 10,000 feet (3,048 meters), 122.4 miles per hour (197.0 kilometers per hour) at 15,000 feet (4,572 meters), 110.0 miles per hour (177.0 kilometers per hours) at 18,000 feet (5,486 meters) and 94.0 miles per hour (151.3 kilometers per hour) at 20,000 feet (6,096 meters). Its cruising speed was 112 miles per hour (180 was kilometers per hour). The airplane could climb to 5,000 feet in 4 minutes, 24 seconds, and to 20,000 feet in 36 minutes, 36 seconds. In standard configuration, the LUSAC 11 had a service ceiling of 20,200 feet (6,157 meters). Its range was 320 miles (515 kilometers).

Armament consisted of two fixed M1918 Marlin .30-caliber machine guns mounted on the right side of the fuselage, synchronized to fire forward through the propeller arc, with 1,000 rounds of ammunition, and two M1918 Lewis .30-caliber machine guns on a flexible mount with 970 rounds of ammunition.

The Air Service had ordered 3,525 of these airplanes, but when the War ended only 28 had been built. The contract was cancelled.

The only Packard Lepère L USA C.II in existence, serial number A.S. 42133, is in the collection of the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

29 January 1926: At McCook Field, near Dayton, Ohio, First Lieutenant John Arthur Macready, Air Service, United States Army, took off in an experimental airplane, the Engineering Division XCO-5. Macready was attempting to exceed the existing Fédération Aéronautique Internationale world altitude record of 12,066 meters (39,587 feet), which had been set by Jean Callizo at Villacoublay, France, 21 October 1924.¹

The official observers of the National Aeronautic Association were Orville Wright (co-inventor with his brother Wilbur, of the airplane); George B. Smith of Dayton; and Levitt Luzurne Custer (inventor of the statoscope, the original barometric altimeter).

The Dayton Daily News reported:

    Every part of the plane functioned perfectly. . . with the exception of the supercharging apparatus. The plane climbed to 25,000 feet in less than 45 minutes. The remainder of the flight was a fight against the dropping pressure in the motor.

     In taking off, the altitude plane required approximately 50 feet and immediately began a steep ascent. Throughout the test the several hundred people who had congregated to see the flight start could find the plane by a long line of white vapor, which trailed in the wake of the ship in the rare atmosphere.

     On other tests the plane has shown sea level pressure at approximately 32,000 feet. The super-charger showed a steadily declining pressure after 25,000 feet, indicating its lack of sufficient capacity for the motor. . .

Dayton Daily News, Vol. XL, No. 162, January 29, 1926, Page 1, Column 7, and Page 2, Column 2

Lieutenant John A. Macready, 28 September 1921. “The cold, though a severe drain on the system with the best protection possible, is more easily met. To prepare for it, Lieutenant Macready wears over his uniform, a heavy suit of woollen underwear and over that a thick heavily padded, leather-covered suit of down and feathers. Then, fur-lined gloves, fleece-lined moccasins over the boots, and a leather head mask lined with fur, which, with the oxygen mask, completely covers the face, completes the costume. The goggles are coated on the inside with anti-freezing gelatine supposed to function to 60 degrees below zero, Fahrenheit.” (NASM)

Lieutenant Macready reported, “My watch stopped at 30,000 feet and I believe it was frozen, because just before landing it started again.” He observed a temperature of -62 °C. (-79.6 °F.) at 34,600 feet (10,546 meters), which he said then increased to -56 °C. (-68.8 °F.) at 36,000 feet (10,973 meters).

When the airplane was inspected after landing at McCook Field, it was found that a crack had developed in the supercharger intercooler, allowing the supercharged air to escape. This resulted in a significant loss of power, and prevented Macready from passing Callizo’s record.

Lieutenant Macready reported that the Fédération Aéronautique Internationale altimeter (one of two altimeters in the airplane’s cockpit) had indicated that he had reached a maximum of 36,200 feet (11,034 meters). When the sealed barograph was sent to the Bureau of Standards in Washington, D.C., for calibration, it indicated a peak altitude of 38,704 feet (11,797 meters). This was 269 meters (883 feet) lower than the existing world record, but it did establish a new United States national altitude record.

Engineering Division XCO-5, A.S. 23-1204. (U.S. Air Force)

The XCO-5 was a prototype two-place, single-engine, two-bay biplane, a reconnaissance and observation variant of the TP-1 fighter. It was built by the Engineering Division at McCook Field. The airplane carried project number P305 painted on its rudder.

The XCO-5’s wings were built specifically for flight at very high altitude, using an airfoil (Joukowsky StAe-27A) designed by Professor Nikolay Yegorovich Zhukovsky (Николай Егорович Жуковский), head of the Central AeroHydroDynamics Institute (TsAGI) at Kachino, Russia. The two-bay biplane wings had a significant vertical gap and longitudinal stagger. The lifting surface was 600 square feet (55.742 square meters). The upper wing had dihedral while the lower wing did not.

The XCO-5 was 25 feet, 1 inch long (7.645 meters) with a wingspan of 36 feet (10.973 meters) and height of 10 feet (3.048 meters). The empty weight was 2,748 pounds (1,246 kilograms) and the gross weight was 4,363 pounds (1,979 kilograms).

The XCO-5 was powered by a water-cooled, 1,649.34-cubic-inch-displacement (27.028 liter) Liberty 12 single overhead cam (SOHC) 45° V-12 engine. It produced 408 horsepower at 1,800 r.p.m. The L-12 is a right-hand tractor, direct-drive engine. As installed on A.S. 23-1204, the engine turned a specially-designed, two-bladed, ground-adjustable, forged aluminum propeller with a diameter of 10 feet, 6 inches (3.200 meters). The Liberty 12 was 67.375 inches (1.711 meters) long, 27.0 inches (0.686 meters) wide, and 41.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).

Also installed on A.S. 23-1204 was an experimental supercharger. FLIGHT explained:

Since the Liberty engine, which delivers 400 h.p. at sea level, has an output of but 50 h.p. at 35,000 feet unsupercharged, a supercharger is a prime requisite of altitude work. The General Electric Form F, 20,000-ft. side type supercharger used in previous tests, with certain modifications, has been installed. The supercharger is an air compressor which keeps the air pressure in the carburettor at sea level pressure at heights where, owing to the natural decrease in the air pressure, the horsepower gradually falls away but to a fraction of its original output. In former supercharger installations, much difficulty was experienced with pre-ignition of the engine. This often became so pronounced that the plane had to be brought to earth. It was suspected that a richer mixture with the supercharger at altitude was necessary. This was found to be true but the principal difficulty was the overheating of the mixture due to the heat generated in the supercharger itself. Due to the increase in temperature created by the compression in the supercharger, it was necessary to interpose an intercooler between the supercharger outlet and the carburettor in order to obtain satisfactory engine performance. The intercooler, in the form of a honeycomb radiator, was placed on the side of the aeroplane. It was also found that the poor conductivity of the air at high altitudes, additional radiating surface for engine cooling was required. This, with the correction of mixture, put an end to pre-ignition.

1st Lieutenant Harold Ross Harris, Air Service United States Army. (San Diego Air and Space Museum Archives)

20 October 1922: 1st Lieutenant Harold Ross Harris, Air Service, United States Army, the Chief, Flight Test Branch, Engineering Division, at McCook Field, Dayton, Ohio, was test flying a Loening Aeronautical Engineering Company PW-2A monoplane, a single-engine, single-seat fighter. The PW-2A, serial number A.S. 64388, had experimental balance-type ailerons. During this flight, Lieutenant Harris engaged in simulated air combat with Lieutenant Muir Fairchild (future Vice Chief of Staff, United States Air Force) who was flying a Thomas-Morse MB-3.

While banking the PW-2A into a right turn, Harris’ control stick began to vibrate violently from side to side and the airplane’s wings were “torn apart.” With the Loening diving uncontrollably, Harris jumped from the cockpit at approximately 2,500 feet (762 meters). After free-falling about 2,000 feet (610 meters), he pulled the lanyard on his parachute which immediately deployed. Harris then descended with his parachute providing aerodynamic deceleration, coming safely to earth in the back yard of a home at 335 Troy Street. He suffered minor bruises when he landed on a trellis in the garden.

Harris’ PW-2A crashed into a yard at 403 Valley Street, three blocks away. It was completely destroyed.

This was the very first time a free-fall parachute had been used in an actual inflight emergency. Lieutenant Harris became the first member of the Irvin Air Chute Company’s “Caterpillar Club.”

The Pittsburgh Post reported:

Flyer Quits Plane in Parachute, Saves Life; Unique Case

     Dayton, O., Oct. 20.—Leaping from his Loenig [sic] monoplace in a parachute when the plane became uncontrollable over North Dayton today, Lieutenant Harold R. Harris, chief of the flying section of McCook Field, escaped death when his plane crashed to earth.

     Technical data, officials at McCook Field said, show that Lieutenant Harris’ escape is the first time an air pilot has ever actually saved himself by use of a parachute. A mail plane flyer leaped in a parachute over Chicago several years ago, but the necessity of his leaving the plane was questioned.

     Harris won the commercial plane event in the Pulitzer races in Detroit last week, flying the “Honeymoon Express” plane.

The Pittsburgh Post, Saturday, 21 October 1922, Vol. 80, No. 303, Page 1, Column 1

Harold R. Harris was born at Chicago, Illinois, 20 December 1895, the first of four children of Ross Allen Harris, M.D., and Mae Ermine Plumb Harris. He enlisted as a private in the Aviation Section, Signal Enlisted Reserve Corps (E.R.C.), 2 May 1917. He was commissioned as a 2nd Lieutenant, Aviation Section, Signal Officers Reserve Corps (O.R.C.) on 15 December 1917. Harris was promoted to the rank of 1st Lieutenant on 19 January 1918. His commission was vacated 18 September 1920 and commissioned as a 1st Lieutenant, Air Service, United States Army, effective 1 July 1920.

Married Grace C. Harris, circa 1920. They had two children.

Ross attended the Air Service Engineering School, graduating in 1922. He also earned a Bachelor of Science degree (B.S.) from the California Institute of Technology, Pasadena, California (“Caltech”).

Harris left the Air Service in 1926. He founded the world’s first aerial crop dusting business, the Huff Daland Company. Next he became a vice president and chief of operations for Grace Airways, a joint venture of Grace Shipping and Pan American World Airways, providing passenger service between South America and the West Coast of the United States.

During World War II, Harris, using his airline experience, helped to establish the Air Transport Command. In 1942, he was commissioned as a colonel in the U.S. Army Air Corps. By 1945, he was Chief, Air Transport Command, with the rank of Brigadier General.

Following World War II, Harris joined American Overseas Airlines, which soon was absorbed by Pan American. Harris was once again a vice president for Pan Am.

In 1955, Harris became president of Northwest Airlines.

Brigadier General Harold Ross Harris, United States Army Air Corps (Retired) died 28 July 1988 at the age of 92 years.

10 October 1928: Flying the Engineering Division-built XCO-5, serial number A.S. 23-1204, Captain St. Clair Streett and Captain Albert William Stevens, Air Service, United States Army, climbed toward the stratosphere.

Captain Stevens was experimenting with the use of photographs of the ground to determine the exact altitude of a high-flying aircraft. He asked Captain Streett to take him as high as possible. “Billy” Streett was Chief of the Flight Branch at Wright Field.

Dressed for the very cold temperatures, Streett and Stevens carried 6 quarts of liquid oxygen in two pressure flasks to breath as it “boiled off.” They started breathing oxygen as they passed 15,000 feet (4,572 meters). Steven’s Fairchild camera was electrically heated. Streett had taken the precaution of drilling two holes in the lenses of his goggles, should they frost over in the extreme cold they would encounter.

It took 1 hour, 40 minutes for the XCO-5 to reach its maximum altitude, which was indicated by the airplane’s altimeter as 40,200 feet (12,253 meters).  The air temperature was -76 °F. (-60 °C.).

After Stevens finished his photography, the pair started their descent. Streett later said,

“Then a strange thing happened. As we coasted down on an easy glide, I started to slow down the motor so that we could keep on descending—and the motor wouldn’t slow! My controls seemed to be stuck, By diving I managed to get down a few thousand feet, but the plane, with its propeller whirring away full tilt, wanted to climb right back up again.

“I didn’t do any more diving. In a frail ship of this special type, the uprush of air in a forced dive would tear off the wings—and I didn’t want to lose them up there! There I was, trying to shut the motor off, and I couldn’t do it!”

Popular Science Monthly, May 1929, Vol. 114, No. 5, Page 23 at Columns 2 and 3

After about twenty minutes, the airplane’s fuel ran low and the engine lost power. It didn’t stop completely, but unable to deliver sufficient power for the XCO-5 to maintain altitude, Streett and Stevens were no longer trapped in the stratosphere.

During the descent, frost formed on Streett’s goggles and he was almost completely blinded, but he was able to something of the ground through the holes in his goggles.

Streett landed in an open field near Rushville, Indiana. They borrowed some gasoline and flew back to Wright Field.

When flight data was analyzed using the Fédération Aéronautique Internationale‘s Standard Atmosphere Method, Streett and Stevens’ maximum altitude was calculated at 37,854 feet (11,538 meters). Steven’s photographic method gave a value of 39,250 feet (11,963 meters). The United States’ National Bureau of Standards used a National Advisory Committee for Aeronautics (NACA) formula to analyze data from two barographs which were on board the XCO-5. This method included temperature and pressure of the atmosphere throughout the climb. The altitude was calculated at 39,606 feet (12,072 meters). This is probably the most accurate determination.

This flight did not set an FAI record. It was approximately 1,000 feet (305 meters) lower than the existing record, and the airplane did not return to the point of departure, a record requirement.

The two-bay biplane wings had a significant vertical gap and longitudinal stagger. The lifting surface was 600 square feet (55.742 square meters). The upper wing had dihedral while the lower wing did not.

The XCO-5 was 25 feet, 1 inch long (7.645 meters) with a wingspan of 36 feet (10.973 meters) and height of 10 feet (3.048 meters). The empty weight was 2,748 pounds (1,246 kilograms) and the gross weight was 4,363 pounds (1,979 kilograms).

The XCO-5 was powered by a water-cooled, 1,649.34-cubic-inch-displacement (27.028 liter) Liberty 12 single overhead cam (SOHC) 45° V-12 engine. It produced 408 horsepower at 1,800 r.p.m. The L-12 is a right-hand tractor, direct-drive engine. As installed on A.S. 23-1204, the engine turned a specially-designed, two-bladed, ground-adjustable, forged aluminum propeller with a diameter of 10 feet, 6 inches (3.200 meters).

Also installed on A.S. 23-1204 was an experimental supercharger.

The XCO-5 has a maximum of 129 miles per hour (208 kilometers per hour) at Sea Level, and a cruise speed of 117 miles per hour (188 kilometers per hour).

Albert William Stevens (Belfast Historical Society and Museum)

Albert William Stevens (née Whitten) was born at Belfast, Maine, 13 March 1886, the third child of Nathan Whitten, a blacksmith and wagon builder, and Alice C. Anderson Whitten. His mother died of “consumption” (tuberculosis) when Albert was five months old. He was adopted by Albert J. Stevens and Nancy M. Trimble Stevens, and his name became Albert William Stevens.

Stevens attended the University of Maine at Orono, Maine. He graduated in 1907 with a Bachelor of Science (B.S.) degree. He earned a Masters degree in electrical engineering  from the university in 1909. He then worked as a mining engineer in Alaska, California, Idaho and Montana.

Stevens enlisted in the U.S. Air Service in Idaho, January 1918. Because of his experience in photography, which began while he was in college, Stevens was assigned to the Aerial Photography School at Cornell University, Ithaca, New York. He was commissioned as a First Lieutenant, Aviation Section, Signal Officers Reserve Corps, 18 February 1918. Sent to Europe as part of the American Expeditionary Forces, Stevens commanded the 6th Photo Section, 88th Aero Squadron. He flew in the major campaigns of the final months of the War.

He was an acknowledged expert in the field of aerial photography. Lieutenant Stevens was wounded and awarded the Purple Heart. Following the War, he was promoted to Captain, Air Service, 21 February 1919. His commission was vacated 18 September 1920, and he was appointed a Captain, Air Service, United States Army, effective 1 July 1920. On 18 November 1922, Stevens was discharged as a Captain, then re-appointed a First Lieutenant.

He returned to the rank of Captain, Air Service, 10 February 1925. On 16 June 1936, he was promoted to the temporary rank of Major, Air Corps, United States Army. This rank became permanent 12 June 1939. In 1940, Major Stevens took command of the Photographer’s School, Air Corps Technical School, Lowry Field, Denver, Colorado. He advanced to the temporary rank of Lieutenant Colonel, 30 December 1940. This rank became permanent 15 October 1941. He was retired from the Air Corps for medical reasons, 30 April 1942.

Stevens married Ruth E. Fischer at Rockville, Maryland, 8 August 1938.

Captain Stevens was a pioneering aviator, balloonist and aerial photographer. Using infrared film, he made the first photograph that showed the curvature of the Earth. He also took the first photograph of the Moon’s shadow on the surface of the Earth during an eclipse.

Stevens made a series of high-altitude balloon flights, and on 11 November 1935 he and Captain Orvil A. Anderson ascended to 22,066 meters (72,395 feet) aboard Explorer II, establishing a Fédération Aéronautique Internationale (FAI) world record.¹

Lieutenant Colonel Andrew William Stevens, United States Army Air Forces (Retired), died at Redwood City, California, 26 March 1949, at the age of 63 years. He is buried at the Golden Gate National Cemetery, San Bruno, California.

18 September 1918: Captain Rudolph William Schroeder, United States Army Air Service, the Chief Test Pilot of the Engineering Division at McCook Field, Fairfield, Ohio, flew a Bristol F.2B fighter to set two Fédération Aéronautique Internationale (FAI) World Records.¹ ²

Aerial Age Weekly reported:

CAPTAIN SCHROEDER ESTABLISHES WORLD ALTITUDE RECORD

THE Contest Committee of the Aero Club of America has homologated the world’s altitude record made by Captain R. W. Schroeder, in a Bristol fighter equipped with a 300 H. P. Hispano-Suiza motor, of 28,900 feet above sea level, during a flight on September 18, 1918, at Wilbur Wright Field, Fairfield, Ohio, near Dayton.

      Nothing was more fitting. While the Allies’ aviators overseas are beating the Germans on the various fronts, an American aviator, Captain R. W. Schroeder, U.S. Air Service, beats the German aeroplane altitude record.

Captain Schroeder left the ground at 1:45 P. M., September 18, 1918. and reached his highest point if 105 minutes, which would have been at about 3:30 P. M. It took him about twenty minutes to descend, landing about 200 miles from where he started, at about 3:50 P. M.

     Captain Schroeder i sin charge of all Performance Tests at the Wilbur Wright Station and his duties require him to go to 21,000 and 22,000 feet quite often, and he generally goes without oxygen. In this record climb, he got well up to 25,000 feet without oxygen. He used no anti-freezing mixture and his maximum water temperature was 85 degrees centigrade at the start minimum and of 60 degrees centigrade at the highest altitude. The temperature of the air was 32 degrees centigrade below zero.

The reports, including the two barograph charts, duly calibrated and corrected: the performance curves, and the temperature record were certified to by Lieut. George B. Patterson, O. I. C. Performance Test Reports and the instruments were calibrated by the Bureau of Standards, and adjusted locally at the McCook Field Laboratory and personally installed on the aeroplane by Lieut. Patterson.

     The previous American altitude record was made by Caleb Bragg at Mineola, L. I., September 20, 1917, in a Wright Martin, Model V machine, when he reached an altitude of 20,250 feet, and the last world’s record of the International Aeronautic Federation made by G. Legagneux in France on the 28th of December, 1913, was 6,120 meters (20,258 feet). In July, 1914, a German aviator was reported as having flown to 26,200 feet, but the record was never submitted for homologation.

     This world’s record, made by Captain Ruddy W. Schroeder, is the first world’s aeroplane altitude record held by an American since the world’s altitude record made by Lincoln Beachey, at Chicago, Ill., during the International Meet, August 20, 1911, when he reached the height of 11,642 feet (3,548 meters).

     Under the rules of the International Aeronautic Federation, the international aeronautic body which controls all aeronautic sports and gives the necessary official records, a pilot must hold the International Aviator’s certificate to have his record recognized. This certificate is issued in the United State by the Aero Club of America, which is the federation’s sole representative in this country. Captain Schroeder held the the F. A. I. certificate at the time he made the record, therefore his record will be accepted by all the countries affiliated with the International Aeronautic Federation and the Pan-American Aeronautic Federation, which represents twenty Latin American republics.

Under the rules of the Federation to establish an altitude record it is necessary to best the old record by at lease 100 meters. Captain Schroeder, therefore, beat the record by a good margin and has gone higher the the highest mountain, with the exception of the highest peak in the Himalaya, which rises 29,002 feet.

     Captain Schroder is a veteran of the aeronautic movement. He is an old time member of the Aero Club of Illinois and well known for his ability as an aviator and aeronautic engineer.

Bristol F.2B C823. (BAE Systems)

The Bristol F.2B was a two-place single-engine two-bay biplane fighter, designed by Captain Frank Sowter Barnwell, O.B.E., A.F.C., and built by the British and Colonial Aeroplane Co., Ltd., Filton and Brislington, Bristol, England, and several other manufacturers. More than 3,800 were produced and some considered it to be the best two-place fighter of the First World War.

The F.2B was 25 feet, 9 inches (7.849 meters) long. Both upper and lower wings had a span of 39 feet, 3 inches (11.979 meters) and a chord of 5 feet, 6 inches (1.676 meters). The total wing area was 405 square feet (37.63 square meters). Both wings had an angle of incidence of 1½°, and 3½° dihedral. There was no sweep. The lower wing was staggered 1 foot, 5 inches (0.432 meters) behind the upper wing. In order to give the gunner a better range of fire, the lower wing was not attached to the bottom of the fuselage. This had the effect of lowering the upper wing while maintaining a vertical gap of 5 foot, 5 inches (1.651 meters).

The gross weight of the F.2B was approximately 2,810 pounds (1,275 kilograms).

Bristol F.2A

The Bristol Fighters were powered by Rolls-Royce Falcon engines. The F.2B was equipped with the Falcon III. The Falcon was a water-cooled, normally-aspirated 867.080-cubic-inch-displacement (14.209 liters) single-overhead camshaft 60° V-12 engine. The Falcon III had a compression ratio of 5.3:1 and had a Sea Level rating of 288 horsepower at 2,300 r.p.m. The propeller gear reduction ratio was 0.589:1.

The F.2B had a maximum speed of 125 miles per hour (201 kilometers per hour) at Sea Level, and 113 miles per hour (182 kilometers per hour) at 10,000 feet (3,048 meters). The fighter could climb to 10,000 feet in 11.5 minutes, and to 15,000 feet (4,572 meters) in 21.5 minutes.

The United States was interested in producing its on version of the F.2B, to be powered by the American Liberty V-12 engine instead of the Rolls-Royce Falcon III V-12. The Royal Air Force sent two F.2Bs to McCook Field to be used as “pattern aircraft.” These were assigned project numbers P30 and P37.³

The Engineering Division at McCook Field found that the Liberty was too heavy to be practical when installed in the Bristol F.2, and other engine types were considered. One of the pattern aircraft was modified to accept a 300 horsepower Hispano-Suiza V-8 engine.

P37 was the project number assigned to the second of the two Bristol F.2B fighters evaluated at Wright Field in 1918.

When equipped with the Hispano-Suiza V-8 engine, the modified F.2B had an empty weight of 1,733 pounds (786 kilograms), and maximum of 2,630 pounds (1,193 kilograms). It had a maximum speed of 128 miles per hour (206 kilometers) per hour at Sea Level; 105 miles per hour (169 kilometers per hour) at 10,000 feet, 100½ miles per hour (162 kilometers per hour) at 13,000 feet, and 97½ miles per hour (157 kilometers per hour) at 15,000 feet. With the Hispano, the F.2B could climb to 1,000 feet in 1 minute, 10 seconds, 10,000 feet in 15 monutes, 5 seconds, 15,000 feet in 28 minutes and 50 seconds.
