United States Army World War I Flight Training

With the purchase of its first airplane, built and successfully flown by Orville and Wilbur Wright, in 1909 the United States Army began the training of flight personnel. This article describes the training provided in those early years, though World War I, and the immediate years after the war until the establishment of the United States Army Air Corps Flight Training Center in San Antonio, Texas during 1926.

Early Signal Corps Flight Training
The history of aviation training in the United States military began on 8 October 1909, when Wilbur Wright began instructing Lieutenants Frank P. Lahm and Frederic E. Humphreys on Signal Corps Airplane No. 1, which the Army had recently purchased from the Wright brothers. Each of the two men received a little over three hours training before soloing on 26 October 1909. The Army airplane trials had been held at Fort Myer, Virginia in 1908 because of its proximity to Washington, headquarters of the Army and its Aeronautical Division, but the commandant at Fort Myer (a cavalry and field artillery post) refused to relinquish the parade ground for further flight training. He was already disgruntled because the trials had disrupted his summer training schedule of mounted drills. Moreover, the Wright Brothers expressed reluctance to teach beginners to fly on the small, enclosed area.

Another site was found near College Park, Maryland, about eight miles northeast of Washington, D.C. The Signal Corps agreed to lease the site. However, the winter weather meant the College Park site could not be used for year-round training. Various sites in the south and west were used during the early 1910s at Fort Sam Houston, near San Antonio, Texas, North Island, San Diego, California, and Augusta, Georgia. However flying training in the Army remained on a small scale until the USA joined World War I in April 1917. In February 1913, the Aviation School contingent in Augusta, Georgia, along with two pilots who had been training in Palm Beach, Florida, transferred to Texas City, Texas, to join ground forces on duty along the border. This meant that the Army Aviation school was concentrated on North Island, San Diego.

World War I Flight Training
When the United States entered World War I, the exhausted British and French forces wanted American troops in the trenches of the Western Front as soon as possible. By 1917, aerial warfare was also considered key to the success of the ground forces, and in May 1917, The French, in particular, asked the Americans to also bolster Allied air power. The French wanted the Americans to supply 5,000 pilots and planes, along with 50,000 mechanics to supplement the French and British air forces already in combat.

The training system of the Signal Corps at that time would simply not be capable of producing such numbers. It was decided to establish a system, similar to the British training program of a ground school, then a primary flight program, then a specialized program to train new pilots in the three basic areas that had been developed by the French and British air forces, pursuit, bombardment and observation.

Preflight Training
The Air Service instituted the first phase of air training, ground schooling, first, because a vast reservoir of eager and qualified young men that volunteered for the Air Service, and also because this phase did not require flight instruction or aircraft. The Signal Corps sent several representatives to the University of Toronto School of Military Aeronautics, where they attended classes, listened to reports from the war zone, and gathered instructional materials and regulations used at the school. The Canadians enrolled a new class every week, graduating students in six weeks' time. Successful ground-school graduates proceeded to flying school. The system served to weed out some unfit or incompetent students early, conserving time and instructional and equipment resources. The American committee decided to adopt the Canadian program in its entirety, only lengthening the course to eight weeks (later extending it to ten weeks, then to twelve), using existing American universities for instruction. During World War I, approximately 23,000 volunteers entered flying cadet training. Eight private and state universities offered preflight (ground school) training. This was conducted at: Upon successful completion of preflight training, flight cadets were sent to Camp John Dick Aviation Concentration Center, located at the Texas State Fairgrounds in Dallas. There the cadets would be processed and placed in groups for their primary flight training.

Primary Training
Primary and advanced training became a major issue with the United States' entry into World War I. In April 1917, the Army had fewer than 100 flying officers and only three flying fields – Hazelhurst Field, Mineola, New York; Camp Kelly, San Antonio, Texas,  and Rockwell Field, San Diego, California. There was also a seaplane base, Chandler Field, Essington, Pennsylvania. However, Chandler Field was closed in the summer of 1917 as inadequate, and its personnel and equipment transferred to the new Gerstner Field, Louisiana. Because it would take a long time to construct adequate training facilities in the United States, Canada provided flying bases at Deseronto and Camp Borden in the Toronto area during the summer of 1917 so that several hundred American cadets could begin primary flying training under the tutelage of the British Royal Flying Corps. The British also operated three flying schools in the United States, located at Camp Taliaferro, Fort Worth, Texas. Among the benefits of the arrangement was the integration of aerial gunnery into the U.S. flight training program. A few Americans who had taken an aerial gunnery course in Canada returned to become instructors at American flying fields. By late 1917, about one-third of Hicks Field, Texas, had been given over to the RFC School of Aerial Gunnery. There, Canadians supplied the planes and equipment to train both Americans and Canadians.

When the United States entered World War I, only the North Island field was a usable military airfield. Essington had been a quarantine station and Mineola, an exposition ground. In May 1917, construction began on Wilbur Wright Field near Dayton, Ohio. Soon afterward, Chanute Field opened at Rantoul, Illinois, as did Selfridge Field near Detroit. By October 31, fourteen facilities had been built, of which nine had begun flight training.

During 1917, a number of fields provided primary training: Hazelhurst Field (Mineola, New York), Selfridge Field (Mt. Clemens, Michigan), Wilbur Wright Field (Fairfield, Ohio), Chanute Field (Rantoul, Illinois), Scott Field (Belleville, Illinois), Camp Kelly (San Antonio, Texas), and Rockwell Field (the old North Island site in San Diego). Proposed advanced schools at Houston, Texas, and Lake Charles, Louisiana, were also used for primary training until the necessary equipment could be supplied for specialized instruction. All of these new airfields were named after Americans who lost their lives on aeronautical duty, some of which in the days when aviation was in its infancy. Three civilians who were pioneers in aeronautics were also honored.

On December 15, 1917, the five northern schools closed and cadets transferred to the two southern schools. Because of year-round training, southern schools permitted a more even flow of students. Each training field consisted of 100 airplanes and 144 cadets, with several training squadrons and a Headquarters and Headquarters Company (HHC).

Between June and late November 1917, manufacturers met the immediate demand for primary trainers with the delivery of 600 new Curtiss JN-4A Jennies, as the airplane became known. The famous Jenny remained the ubiquitous primary trainer throughout the war. Depending upon the vagaries of weather, equipment, and individual ability, the aspiring pilot needed six to eight weeks, including forty to fifty hours of flying time, to earn his wings.

Advanced Training
Over 11,000 flying cadets received their wings and were commissioned before entering four weeks of advanced training. Advanced training in the United States adopted the scheme used by tactical squadrons in France of classifying flying personnel (pilots or observers, the latter including all non-pilots) according to mission.
 * Pursuit instruction took place at Rockwell Field, Carlstrom Field, and Dorr Field
 * The pursuit pilot, flying a single-seat aircraft, usually at high altitude, was the fighter. The approximately nine-week pursuit course encompassed theoretical and practical ground and air training. Ground instruction included study of the organization and employment of pursuit squadrons; the types and assembly of motors, airplanes, and radios; formation flying; German military organization, tactics, and combat aircraft; and fighting methods, maneuvers, attack, and combat, while alone and in formations.


 * Observer instruction took place at Call Field, Post Field, Langley Field, and Selfridge Fields.
 * The observation pilot was accompanied by an aerial observer who gathered information and photographed enemy positions. Although the observation mission was familiar, for the first time the Air Service had to craft formal crew training curricula. Besides pilots transitioning to new aircraft, non-pilot observers had to be instructed how to gauge the enemy’s activities and to photograph and, frequently, to shoot. Thus, in addition to programs for piloting and gunnery – the two elements of pursuit training – observation required teaching the additional skills of radio communication, photography, and artillery spotting.


 * Bombing instruction took place at Ellington Field and Gerstner Fields.
 * The bombing pilot and bombardier also flew a double-seat airplane across enemy lines, often at night. Because the Army leadership so tardily and reluctantly developed bombardment as an acknowledged branch of aerial warfare, it was the last section to be organized, and it initially lacked most essential equipment. But it was also subject to less pressure since the AEF requested only two bombing pilots for every five pursuit and three observation pilots.  Classwork included the study of organizations, map and compass reading, ballistics, photography, tactics, day and night bombing, preparations for raid, miniature range exercises, and study of and then actually dropping dummy and explosive bombs. After commissioning, the bombardier and the pilot held equal rank, and both continued for two more weeks of aerial gunnery training.

Supposedly, all combat airmen had taken some aerial gunnery instruction. Advanced gunnery therefore followed the pursuit pilot at the pursuit schools and the others at advanced aerial gunnery schools. The burden on the Army, as it tried to build the capability for advanced training in the United States, was ultimately insurmountable. Airfields might be used for primary as well as for advanced training, or they might be converted from one type to the other as weather conditions dictated, as equipment became available, or as demand for specialists increased or decreased.

By the end of May 1918, a bombing school was located at Ellington Field near Houston; a pursuit school at Gerstner Field, Lake Charles, Louisiana, and three other fields to be converted from primary to pursuit; observer schools were at Langley Field, Virginia, and at Post Field, Fort Sill. There were gunnery schools at Selfridge Field, Mt. Clemens, Michigan; at Ellington Field; at Taliaferro Field No. 1, Fort Worth, Texas; and at Wilbur Wright Field, Fairfield, Ohio, which also served as an armorers' and instructors' school. The Training Section also established auxiliary schools at Wilbur Wright Field taught armorers, Brooks Field and Scott Field contained the principal instructor's schools. Radio instruction was taught at Carnegie Tech University, Pittsburgh, Austin University, Texas and Columbia University, New York. A photography school at Langley Field was also developed.

Because the United States was in World War I only for a year and a half and entered it so unprepared, only about 1,000 of the 11,000 aviators trained during the war were actually involved in operations against the enemy. Most of these operations consisted of artillery observation or air-to-air combat. Rapid demobilization followed the end of World War I, and many of these flying schools were closed and turned over to local authorities as airports, although some remained in service though the 1920s, World War II, and into the modern era.

American Expeditionary Force Training
Upon deployment to France, additional training was conducted by a series of Air Instructional Centers (AIC)s in France using French and British aircraft that were used in the combat squadrons at the front. This supplemental training was provided because of a lack of necessary equipment in the United States.

Early intentions to conduct only advanced training in Europe immediately went awry. Because the structure for primary flight training had yet to be erected in the United States and because European facilities appeared to have space, it was arranged for several hundred American cadets to be admitted to French training schools, and he contacted the British and Italians to obtain similar commitments. The English accommodated about 200 men, and approximately 500 cadets went to Foggia, Italy, for primary training. The largest number of men found themselves in France. The Air Service partially gave over the Third Aviation Instruction Center (3d AIC) at Issoudun Airdrome, France, originally intended for advanced instruction, to primary training. Negotiations for aviation schools at Tours Airdrome and Clermont-Ferrand Airdrome to be turned over to the U.S. Army – the former for observation and the latter for bombardment – were also in progress. But Tours, too, was converted to primary training. The old French aero school, located on a plateau across the river at Tours, came into American hands as the 2d AIC in September, and it remained the principal American primary flying school in France until the program's end.

Tours and Issoudun conducted primary training for as many cadets as possible, even though some were left to languish, while other European schools also accepted trainees at overflow levels. Some new arrivals stayed at the Beaumont Barracks in Tours; others lodged at St. Maixent; still others were quartered at AEF headquarters in Paris. In January, 1918 the Training Section attempted to introduce some order by having all untrained cadets, of whom no more were authorized, removed from the schools and sent to St. Maixent, site of an old French barracks. It was to serve as the concentration point for all aviation troops arriving in the AEF.

The French employed a variety of aircraft, in combat and in training. Americans at Avord learned on the Bleriot or the Caudron; promising cadets then passed to the much admired Nieuport for advanced pursuit training.I4 The French could most easily spare the Caudron G-3 for the American primary school at Tours, which was itself modeled directly on the Caudron course at Avord. The Caudron G-3 was a single-engine reconnaissance airplane of 1914 vintage, already outmoded by bomber models developed from it.

The Italians agreed to host as many as 500 cadets in a school at Foggia, about 200 miles southeast of Rome.” In September 1917, the school, officially the 8th AIC under joint American and Italian jurisdiction, began training the first detachment of forty-six cadets, all honor graduates of American ground schools. The detachment had been sent first to Avord, but when plans for training in Italy crystallized.

The school was overcrowded and was lacking in proper quarters and mess facilities for the Americans. Also a lack of English-speaking instructors led to the decision to withdraw the Americans from the school. Students were sent to the 3d AIC at Issodun, with the last departing on 4 December 1917.

Postwar reorganization
In early 1919 the Air Service's hopes ran high. The War Department determined to purchase and maintain fifteen flying fields and five balloon schools for training purposes. Of those, the government already owned Rockwell, Langley, Post (at Fort Sill), and Kelly Field No. 1.  Early plans anticipated opening several primary schools and separate sites for advanced training in bombardment, observation, pursuit, and gunnery. However rapid peacetime demobilization led to the closure of the leased wartime facilities and by the end of 1919 most were deactivated as an active duty airfields, and a small caretaker unit was assigned to the facilities for administrative reasons.
