Early years Although the United States Armed Forces had been evaluating aircraft since Lt.
Benny Foulois flew with
Orville Wright in 1909, the designation of "test pilot" was not formally applied until a group of
McCook Field pilots was assigned to a flight testing squadron at
Wright Field during
World War I. Test pilot selection was a seemingly indiscriminate process yielding a mix of experienced pilots who had volunteered for the task, flight instructors who were simply assigned to the job, and the occasional officer fresh from flying school. One of the latter, Lt.
Donald Putt, who would later rise to the rank of lieutenant general, recalled: Test pilot training was nearly as informal as the selection process with most material directed toward the aeronautical engineers who supervised the tests. Reports and texts of this time provided little guidance regarding how tests should be flown. The best training for test pilots came from practical experience gained while flying as observers and hangar-talk tutorials from other pilots. A test pilot was not expected to have a formal engineering background. He was simply to follow the instructions on the test card and fly the airplane appropriately. Today, most
test pilots have advanced degrees in engineering.
At Wright-Patterson AFB Inspired by the
RAF's
Empire Test Pilots' School, Colonel
Ernest K. Warburton, chief of the Flight Test Section at
Wright Field, set about changing the role and status of flight testing in the
Army Air Forces. His goals for the flight test community were standardization and independence, which were later realized with the establishment of the Air Technical Command Flight Test Training unit on 9 September 1944 Under the command of Major Ralph C. Hoewing, the Flight Test Training Unit's curriculum included classroom sessions covering performance flight test theory and piloting techniques. The students then put theory into practice with performance evaluations on the
AT-6 Texan trainer. Shortly after the first class graduated, the school was redesignated the Flight Section School Branch with an increased focus on academic theory. In 1945, the school moved to Vandalia Municipal Airport (now the
Dayton International Airport), after which it was redesignated the Flight Performance School and placed under the command of Lt. Colonel John R. Muehlberg, who became the first to carry the title "
commandant". Little is known about the second class of students (the first class at Vandalia), but according to Robert "Bob" Rahn in his book Tempting Fate, he identified four pilots who were in this class: , , , and Robert "Bob" Rahn. The class designation for this class is not known. Under Muehlberg, who in 1944/45 had attended the second course at the newly established ETPS in England, the school increased its fleet with
North American P-51 Mustangs,
Boeing B-17 Flying Fortress, and
North American B-25 Mitchells and expanded the curriculum to include a separate four-month stability and control course in addition to the existing performance course. In 1946, the test pilot school was moved again to nearby
Patterson Field and Colonel
Albert Boyd was assigned as chief of the Flight Test Division. Col. Boyd profoundly influenced both the school and the character of its future AAF test pilots with his insistence on precision flying skills and discipline. A graduate of the school in 1946, Major
Bob Cardenas, later summarized Col. Boyd's influence:
Heading west Frequent bad weather and increased air traffic congestion at
Wright-Patterson often prevented students from completing their coursework on time. In addition, most
USAAF airplanes were by then being manufactured and tested by contractors on the
West Coast of the United States. For these and other reasons, Col. Boyd began the transfer of all flight test operations, including the test pilot school, to Muroc Army Air Field. next to
Rogers Dry Lake in the desert of southern
California. and the first class to fly jets. The
Lockheed P-80 Shooting Star would provide jet performance training at the school until 1954. On 8 December 1949, Muroc AFB has renamed the
Edwards Air Force Base in honor of
Glen Edwards, TPS class 45, who was killed in the crash of the
Northrop YB-49 Flying Wing bomber. Captain Edwards, who had recently earned a Master of Science degree in
aeronautical engineering from
Princeton, typified the new breed of test pilot of which Cardenas had written — one who combined the talents of a highly skilled pilot with the technical expertise of an engineer. Amman completed his work and on 4 February 1951, the school was officially transferred to Edwards Air Force Base. The enormous dry lake bed, extremely long runways, and clear weather served the USAF and the school well, as aircraft performance continued to increase. The TPS was housed in an old weather-beaten wooden hangar along the flight line of what became known as South Base. Some students were not prepared for the rigorous academics and had to be dropped from enrollment. This situation improved in 1953, when the school was moved out of Air Research and Development Command, which allowed the selection boards to draw from a much larger, USAF-wide, pool of applicants, rather than just the local test squadrons. In 1955, the school was renamed the U.S. Air Force Flight Test Pilot School, and a year later, moved into its present location on the Main Base facility. In 1956, the school chose an official emblem, featuring a slide rule in front of the silhouette of a climbing jet, and a motto,
Scientia est Virtus — Latin for "Knowledge is Power". The new logo emphasized the school's role in preparing students with both the technical theory and flying skills indispensable for evaluating modern aircraft. Between 1962 and 1975, the test pilot school expanded its role to include astronaut training for armed forces test pilots. Thirty-seven TPS graduates were selected for the U.S. space program, and 26 earned astronaut's wings by flying in the
X-15,
Gemini,
Apollo, and
Space Shuttle programs. On 21 May 2009, a
T-38 Talon from the test pilot school on a training flight crashed 12 miles north of Edwards AFB, killing the student pilot Major Mark Paul Graziano and severely injuring the student navigator Major Lee Vincent Jones. An accident investigation determined that the crash was caused when the aircraft's rudder operating mechanism disconnected the flight controls from the rudder actuators and caused the rudder to deflect 30° to the left. This induced an uncontrollable yaw and a resulting roll, causing the aircraft to depart a controlled flight, a condition that is unrecoverable in the T-38. The report stated that contributing factors to the crash were a structural fatigue failure or a structural break in a critical component or bolt, and a maintenance error in which a nut or cotter pin did not properly secure a bolt connecting two critical components. Citing two historical cases of rudder failure, the report concluded that maintenance error was the more likely cause. The investigation concluded, "insufficient supervisory oversight and a lack of discipline of the training process" in the maintenance unit existed in relation to the mishap aircraft. ==Personnel==
