17 January 1932: The 11th Bombardment Squadron, U.S. Army Air Corps, commanded by 1st Lieutenant Charles H. Howard and based at March Field, Riverside, California, flew six Curtiss B-2 Condor bombers to drop food and supplies to the Navajo reservation near Winslow, Arizona. A severe winter storm had isolated the community and caused the deaths of thousands of livestock.

More than 30,000 pounds (13,600 kilograms) of food was dropped to support the 20,000 people of the Navajo and Hopi nations effected by the winter storms.

Lieutenant Howard and the 11th Bombardment Squadron won the Mackay Trophy for the most meritorious flight of the year. This was the first time that the Mackay was awarded to a group.

Charles Harold Howard was born at Ashland, Oregon, 29 December 1892. He was the first of two children of Charles B. Howard, a telegraph operator, and Mary Ann Kincaid Howard.

Howard enlisted as a private in the Signal Corps, United States Army, 23 November 1917. He served with Company C, 322nd Field Signal Battalion, and the Aviation Section, Signal Corps. He was commissioned as a second lieutenant, Air Service, 7 November 1918.

In 1920, Lieutenant Howard was an instructor at the Air Service Flying School at Love Field, Dallas, Texas. In a reorganization of the Air Service, his commission was vacated 15 September 1920 and he was appointed a second lieutenant, Air Service, with date of rank retroactive to 1 July 1920. Howard was promoted to first lieutenant, 30 August 1924.

Captain Howard was killed in an aircraft accident near Bryan Mill, Texas, 25 October 1936. His remains were buried at the Mountain View Cemetery, Ashland, Oregon. Howard Air Force Base, Panama, was named in his honor.

The following is excerpted from the Davis-Monthan Aviation Field Register web site:

The Air Corps Newsletter of November 1, 1936 reports his passing and summarizes his flying career:

“An airplane accident on the night of October 25th, near Bryan’s Mill, Texas, cost the lives of Captain Charles H. Howard and Corporal Edward N. Gibson, Air Corps, both of whom were stationed at Langley Field, VA.

“Captain Howard, who enlisted in the Aviation Section, Signal Corps, during the World War, was an efficient and capable officer, an expert pilot, and was particularly well versed in the field of radio communications.

“. . . after serving for a brief period with Company C, 322nd Field Signal Battalion, Fort Lewis, Washington, he was transferred to Kelly Field, Texas, where he served with the 84th Aero Squadron. . .

“During the next four years, Captain Howard’s duties related mainly to radio communications. . . 

“In January 1926, Captain Howard was transferred to the Panama Canal Department, where he served for three years, being on duty with the 7th Observation Squadron at France Field for two years, and with the 25th Bombardment Squadron in the remaining year.

“From Panama, Captain Howard was transferred to Rockwell Field, Calif., when he was assigned to the 11th Bombardment Squadron. He also served as Communications Officer of the 7th Bombardment Group. Later, when the Squadron was transferred to March Field, Calif., he was placed in command thereof.”

It was during this time that he and his crew won the Mackay Trophy.

“During the summer of 1934, Captain Howard piloted one of the B-10 Bombardment planes in the Army Alaskan Flight, from Washington, D.C., to Fairbanks, Alaska, and return. This aerial expedition of ten B-10 airplanes was commanded by Brigadier General Henry H. Arnold. The flight was completed according to a prearranged schedule in exactly one month. In addition to his duties as pilot, Captain Howard served as Assistant Communications Officer of the expedition. . .

“Captain Howard had to his credit over 4,000 hours flying time. He was the author of various articles dealing most interestingly and convincingly with subjects in which he particularly specialized – Bombardment Aviation and Radio Communications.”

The Curtiss B-2 Condor was a large (by contemporary standards) twin-engine biplane bomber, operated by a crew of five. It was 47 feet, 4.5 inches (14.440 meters) long with a 90 foot (27.432 meter) wingspan and overall height of 16 feet, 6 inches (5.029 meters).

The B-2 was powered by two liquid-cooled, normally-aspirated 1,570.381-cubic-inch-displacement (25.734 liter) Curtiss Conqueror V-1570-7 DOHC 60° V-12 engines producing 633 horsepower at 2,450 r.p.m., each, driving three-bladed propellers.

The airplane had an empty weight of 9,300 pounds (4,218.4 kilograms) and loaded weight of 16,591 pounds (7,525.6 kilograms).

The bomber had a maximum speed of 132 miles per hour (212 kilometers per hour) at Sea Level and a range of 805 miles (1,296 kilometers).

Although the Condor’s service ceiling was 16,140 feet (4,920 meters), Lieutenant Howard flew one to 21,000 feet (6,400 meters) while conducting an experiment in cosmic ray research for Dr. Robert Andrews Millikan of Caltech, Pasadena, California. (“Service ceiling” is the altitude above which an aircraft can no longer maintain at least a 100 feet per minute/0.5 meters per second rate of climb.)

Defensive armament consisted of six .30-caliber Lewis machine guns, with gunners’ positions at the nose and behind each engine. The B-2 could carry 2,500 pounds (1,134 kilograms) of bombs.

Including the XB-2 prototype, 13 B-2s were built, and a single B-2A. They were removed from service by 1934 as more modern designs became available.

16 January 1957: Operation Powerflite. At 1:00p.m. PST, five Boeing B-52B Stratofortress eight-engine jet bombers of the United States Air Force Strategic Air Command, 93rd Bombardment Wing (Heavy), departed Castle Air Force Base, near Merced, California, on a non-stop around-the-world flight. 45 hours, 19 minutes later, three B-52s landed at March Air Force Base, Riverside, California, completing the 24,325 miles (39,147 kilometer) flight at an average speed of 534 miles per hour (859 kilometers per hour). Two of the bombers had mechanical problems. One returned to the United States and one landed in England.

The lead Stratofortress, B-52B-35-BO 53-0394, Lucky Lady III, was commanded by Lieutenant Colonel James H. Morris. Morris had been co-pilot aboard Lucky Lady II, a Boeing B-50A Superfortress that flew around the world in 1949. Also aboard Morris’ bomber was Major General Archie J. Old, Jr., commanding 15th Air Force. The other two B-52s were 53-0397, La Victoria, commanded by Major George Kalebaugh, and 53-0398, Lonesome George, commanded by Captain Charles W. Fink.

Each B-52 carried a flight crew of nine men, including three pilots and two navigators.

Four inflight refuelings from piston-engine Boeing KC-97 Stratotankers were required.

All 27 crewmembers of the three bombers were awarded the Distinguished Flying Cross by General Curtis LeMay. The Mackay Trophy for “the most meritorious flight of the year” was awarded to the 93rd Bombardment Wing.

The 93rd Bombardment Wing (Heavy) was the first operational Air Force unit to receive the B-52 Stratofortress, RB-52B 52-8711, on 29 June 1955. Fifty B-52Bs were built by Boeing at its Plant 2, Seattle, Washington. The B-52B/RB-52B was operated by a six-man flight crew for the bombing mission, and eight for reconnaissance. These were the aircraft commander/pilot, co-pilot, navigator, radar navigator/bombardier, electronic warfare officer and gunner, plus two reconnaissance technicians when required.

The airplane was 156 feet, 6.9 inches (47.724 meters) long with a wingspan of 185 feet, 0 inches (56.388 meters) and overall height of 48 feet, 3.6 inches (14.722 meters). The wings were mounted high on the fuselage (“shoulder-mounted”) to provide clearance for the engines which were suspended on pylons. The wings’ leading edges were swept 35°. The bomber’s empty weight was 164,081 pounds (74,226 kilograms), with a combat weight of 272,000 pounds (123,377 kilograms) and a maximum takeoff weight of 420,000 pounds (190,509 kilograms).

Early production B-52Bs were powered by eight Pratt & Whitney J57-P-1W turbojet engines, while later aircraft were equipped with J57-P-19W and J57-P-29W or WA turbojets. The engines were grouped in two-engine pods on four under-wing pylons. The J57 was a two-spool, axial-flow engine with a 16-stage compressor section (9 low- and 7-high-pressure stages) and a 3-stage turbine section (1 high- and 2 low-pressure stages). These engines were rated at 10,500 pounds of thrust (46.71 kilonewtons), each, or 12,100 pounds (53.82 kilonewtons) with water injection.

The B-52B had a cruise speed of 523 miles per hour (842 kilometers per hour). The maximum speed varied with altitude: 630 miles per hour (1,014 kilometers per hour) at 19,800 feet (6,035 meters), 598 miles per hour (962 kilometers per hour) at 35,000 feet (10,668 meters) and 571 miles per hour (919 kilometers per hour) at 45,750 feet (13,945 meters). The service ceiling at combat weight was 47,300 feet (14,417 meters).

Maximum ferry range was 7,343 miles (11,817 kilometers). With a 10,000 pound (4,536 kilogram) bomb load, the B-52B had a combat radius of 3,590 miles (5,778 kilometers). With inflight refueling, the range was essentially world-wide.

Defensive armament consisted of four Browning Aircraft Machine Guns, Caliber .50, AN-M3, mounted in a tail turret with 600 rounds of ammunition per gun. These guns had a combined rate of fire in excess of 4,000 rounds per minute.

The B-52B’s maximum bomb load was 43,000 pounds (19,505 kilograms). It could carry a 15-megaton Mark 17 thermonuclear bomb, or two Mark 15s, each with a maximum yield of 3.8 megatons.

Boeing manufactured 744 B-52 Stratofortress bombers, with the final one rolled out at Wichita, Kansas, 22 June 1962. As of 27 September 2016, 77 B-52H bombers remain in service with the United States Air Force.

15 January 1915: At San Diego, California, Lieutenant Byron Quinby Jones, Aviation Section, Signal Corps, United States Army, set a flight endurance record of 8 hours, 53 minutes, flying a Glenn L. Martin Company Martin T Army Tractor. The flight consumed 30 gallons (114 liters) of gasoline. Lieutenant Jones estimated that he had sufficient fuel remaining for another two hours in the air, but approaching darkness forced him to land.

For this and other flights at San Diego, Lieutenant Jones was awarded the Mackay Trophy.

The Mackay Army Aviation Cup was established in 1911 by Clarence Hungerford Mackay, Chairman of the Board of Directors of the Postal Telegraph and Cable Corporation. Now known as the Mackay Trophy, it is awarded yearly for “the most meritorious flight of the year” by U.S. Air Force personnel.

Lieutenant Jones was the sixth aviator to be awarded the trophy. The trophy is kept at the Smithsonian Institution National Air and Space Museum. It was appraised in the 1960s at a value of $65,000, though it was also estimated that it would cost $650,000 to duplicate it.

Byron Quinby Jones was born at Henrietta, New York, 9 April 1988. He was one of four children of Samuel Titus Jones and Sarah Minerva Quinby Jones. He attended School 24 and East High School, Rochester, New York. Jones entered the United States Military Academy, West Point, New York, 15 June 1907, and graduated 12 June 1912 with a bachelor of science degree. He was commissioned as a second lieutenant in the 14th Cavalry Regiment, United States Army.

Lieutenant Jones volunteered for pilot training and was sent to the Signal Corps Aviation School at North Field, San Diego, California. After earning a rating as one of the earliest U.S. military pilots and serving for a year with an active squadron, Jones was promoted to the rank of first lieutenant, Aviation Section, Signal Corps, 23 November 1914. He was then sent to the Massachusetts Institute of Technology (MIT) for the very first post-graduate course in aeronautical engineering.

In addition to he endurance records, “B.Q.” Jones was also the first Army pilot to perform a loop, an intentional stall and recovery, and a “tail spin.”

During World War I, Jones rose to the temporary rank of lieutenant colonel.

Jones married Mrs. Evelyn Clark Chadwick (née Evelyn Kennerly Clark, grandaughter of William Clark, co-leader with Meriwether Lewis of the 1804–1806 Lewis and Clark Expedition), 4 June 1917.

For the next twenty-four years, Jones steadily rose in rank and was an important figure in Army aviation. Assigned to the newly established Air Service, Jones was promoted to the rank of major, 1 July 1920, and lieutenant colonel, 1 August 1935.

In 1939, because of a disagreement with senior Air Corps officers over military aviation doctrine, he requested a return to the Cavalry. He was promoted to the rank of colonel, Army of the United States, 16 November 1940, and colonel, United States Army, 1 February 1942.

Byron Jones graduated from the Army Industrial College in 1926, Command and General Staff School, 1927, and the Army War College, 1929.

Colonel Jones was a leader in forming a mechanized cavalry and combined arms service. During World War II, he served in the Guadalcanal Campaign, and the staff of General Douglas MacArthur in Australia. He then held several assignments within the continental United States. He was hospitalized for lengthy periods several  times, and finally was discharged from the Army, 31 January 1944.

Colonel Byron Quinby Jones, United States Army (Retired), died at Walter Reed Army Hospital, 30 March 1959, at the age of 70 years. His remains were interred at the Arlington National Cemetery.

The Martin T was a two-place, single-engine biplane ordered as a trainer for the Signal Corps. Three were built and given serial numbers S.C.31–33. The airplane was a tractor configuration, with an engine and propeller at the front of the fuselage, rather than behind in a pusher configuration. The Martin T also had a wheeled tricycle undercarriage. Both of these features were relatively new and would become standard.

The Pulitzer Trophy

12 October 1925: At Mitchel Field, Long Island, New York, Lieutenant Cyrus Bettis, Air Service, United States Army, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over 100 kilometers (62.14 miles), flying a Curtiss R3C-1 racing plane, #43. His average speed was 401.28 kilometers per hour (249.34 miles per hour).¹ Lieutenant Bettis was awarded the Pulitzer Trophy.

Bettis also won the Mackay Trophy for 1925.

Cyrus Bettis had previously won the 1924 Mitchell Trophy Race, sponsored by Brigadier General Billy Mitchell in honor of his brother, John L. Mitchell, who was killed during World War I.

The Curtiss R3C-1 was a single-place, single-engine, single-bay  biplane built for especially for air racing.  Two were built for the United States Navy and one for the Army. (The Army aircraft is identified by a Navy Bureau of Aeronautics serial number (“Bu. No.”) A-7054. It does not seem to have been assigned an Air Service serial number.) The airplane and its V-1400 engine were built by the Curtiss Aeroplane and Motor Company, which had been founded by Glenn Hammond Curtiss. It was converted to a seaplane configuration with two single-step pontoons, the R3C-2, for the Schneider Trophy Race, two weeks later, 25 October.

The R3C is 19 feet, 8½ inches (6.007 meters) long. The upper wing span is 22 feet (6.706 meters), with a chord of 4 feet, 8¼ inches (1.429 meters). The lower wing span is 20 feet (6.096 meters) with a chord of 3 feet, 3¾ inches (1.010 meters). The R3C-1 had an empty of 2,135 pounds (968 kilograms) and its maximum takeoff weight was 2,738 pounds (1,242 kilograms).

Constructed of wood, the fuselage had four ash longerons and seven birch vertical bulkheads. The framework was covered with two layers of 2-inch (51 millimeter) wide, 3/32-inch (2.38 millimeter) thick spruce strips. These were placed on a 45° diagonal from the fuselage horizontal centerline, with the second layer at 90° to the first. These veneer strips were glued and tacked to the frame. The fuselage was then covered with doped fabric. The wings and tail surfaces were also of wood, with spruce ribs and a covering of spruce strips.

The single-bay wings were wire braced and contained surface radiators made of thin brass sheeting. The radiators contained 12 gallons (45.4 liters) of water, circulating at a rate of 75 gallons (283.9 liters) per minute. By using surface radiators to cool the engine, aerodynamic drag was reduced.

The Curtiss V-1400 engine was developed from the earlier Curtiss D-12. It was a water-cooled, normally aspirated, 1,399.91-cubic-inch-displacement (22.940 liter), dual overhead cam (DOHC) 60° V-12, with a compression ratio of 5.5:1. The V-1400 was rated at 510 horsepower at 2,100 r.p.m., and could produce 619 horsepower at 2,500 r.p.m. It was a direct-drive engine and turned a two-bladed duralumin fixed-pitch propeller with a diameter of 7 feet, 8 inches (2.337 meters). The propeller was designed by Sylvanus Albert Reed, Ph.D. The V-1400 engine weighed 660 pounds (299 kilograms).

The R3C-1 had a fuel capacity of 27 gallons (102 liters). Its range was 290 miles (467 kilometers).

After the Pullitzer race, the R3C-1 was reconfigured as a seaplane for the Schneider Trophy Race. The fixed landing gear was replaced by two single-step pontoons and the airplane was redesignated R3C-2. Additional fuel was carried in the pontoons. On 26 October 1925, 1st Lieutenant James H. Doolittle flew the airplane to win the Coupe d’Aviation Maritime Jacques Schneider at Chesapeake Bay, Maryland.

The R3C-2 is in the collection of the Smithsonian Institution National Air and Space Museum.

Cyrus Bettis was born 2 January 1893, at Carsonville, Michigan, the first of three children of John Bettis, a farm worker, and Mattie McCrory Bettis.

Bettis enlisted as a private, first class, in the Aviation Section, Signal Enlisted Reserve Corps, at Detroit, Michigan, 23 January 1918. The Bell Telephone News reported:

     Cyrus Bettis has gone to Detroit and enlisted in the Aviation Corps of Uncle Sam’s service.

     He expects to be called to service at any time and will probably go East for training. Cyrus has been the efficient and genial manager of the Michigan State Telephone exchange in Fenton for several years. He has made an excellent manager and entrenched himself in the good graces of his patrons and Fenton People in General. —Fenton Independent.

Bell Telephone News, Volume 7, Number 6, January 1918, at Page 4, Column 1

On 11 September 1918, Cyrus Bettis was commissioned as a second lieutenant, Air Service, United States Army. This commission was vacated 16 September 1920 and he was appointed a second lieutenant, Air Service, with date of rank to 1 July 1920. On 21 March 1921, Bettis was advanced to the rank of first lieutenant, retroactive to 1 July 1920.

On 23 August 1926, flying from Philadelphia to Selfridge Field in Michigan, Bettis flew into terrain in fog in the Allegheny Mountains of western Pennsylvania. With a fractured skull and broken left leg, Bettis crawled several miles to a roadway where he was found, 43 hours after the crash.

Bettis was taken by air ambulance to Walter Reed Army Hospital, but died of spinal meningitis resulting from his injuries, 1 September. He was buried at the Lakeside Cemetery, Port Huron, Michigan.

9 October 1912: In October, Lieutenants Henry H. Arnold and Thomas DeWitt Milling, both assigned to the Aeronautical Division, Signal Corps, United States Army, were ordered to enter the competition for the first Mackay Trophy for “the most outstanding military flight of the year.” Milling withdrew because of illness shortly after the competition started.

“Hap” Arnold won when he flew a 40-horsepower Wright Model B biplane over a triangular course from College Park to Washington Barracks at Washington D.C., on to Fort Myers, Virginia, and back to College Park.

The Mackay Trophy was established on 27 January 1911 by Clarence Hungerford Mackay, who was then head of the Postal Telegraph-Cable Company and the Commercial Cable Company. Originally, aviators could compete for the trophy annually under rules made each year, or the War Department could award the trophy for the most meritorious flight of the year.

The Wright Model B was a two-place, single-engine biplane. The elevator was at the rear, rather than in canard position as had been the earlier Wright airplanes. (This configuration was known as “headless.”) Roll control was through the Wright Brother’s wing-warping system. The Model B was 26 feet (7.925 meters) long with a wingspan of 39 feet (11.887 meters). It had an empty weight of 800 pounds (363 kilograms) and a gross weight of 1,250 pounds (567 kilograms).

The Model B was powered by a water-cooled, fuel-injected, 240.53-cubic-inch-displacement (3.942 liter), Wright “4-40” inline four-cylinder overhead valve gasoline engine, which produced 32 horsepower at 1,310 r.p.m. The engine weighed 160 pounds (73 kilograms). Two 8½ foot (2.591 meters) diameter, two-bladed, counter-rotating propellers, driven by a chain drive, are mounted behind the wings in pusher configuration. They turned 445–470 r.p.m.

The Wright Model B had a maximum speed of approximately 40 miles per hour (64 kilometers per hour) and its range was 110 miles (177 kilometers).

Approximately 100 Model B aeroplanes were built by the Wrights and under license by Burgess from 1910 to 1914. Three are known to exist.

Arnold won the Mackay Trophy again in 1934 when he commanded a flight of ten Martin B-10 bombers from Bolling Field, Washington, D.C., to Fairbanks, Alaska, and back.

Lieutenant Arnold went on to have a successful career in military aviation.
