Problem: Background: Herbert Alexander Simon (June 15, 1916 - February 9, 2001) was an American economist and political scientist whose primary interest was decision-making within organizations and is best known for the theories of "bounded rationality" and "satisficing". He received the Nobel Prize in Economics in 1978 and the Turing Award in 1975. His research was noted for its interdisciplinary nature and spanned across the fields of cognitive science, computer science, public administration, management, and political science. He was at Carnegie Mellon University for most of his career, from 1949 to 2001.
Context: Simon was a pioneer in the field of artificial intelligence, creating with Allen Newell the Logic Theory Machine (1956) and the General Problem Solver (GPS) (1957) programs. GPS may possibly be the first method developed for separating problem solving strategy from information about particular problems. Both programs were developed using the Information Processing Language (IPL) (1956) developed by Newell, Cliff Shaw, and Simon. Donald Knuth mentions the development of list processing in IPL, with the linked list originally called "NSS memory" for its inventors. In 1957, Simon predicted that computer chess would surpass human chess abilities within "ten years" when, in reality, that transition took about forty years.  In the early 1960s psychologist Ulric Neisser asserted that while machines are capable of replicating "cold cognition" behaviors such as reasoning, planning, perceiving, and deciding, they would never be able to replicate "hot cognition" behaviors such as pain, pleasure, desire, and other emotions. Simon responded to Neisser's views in 1963 by writing a paper on emotional cognition, which he updated in 1967 and published in Psychological Review. Simon's work on emotional cognition was largely ignored by the artificial intelligence research community for several years, but subsequent work on emotions by Sloman and Picard helped refocus attention on Simon's paper and eventually, made it highly influential on the topic.  Simon also collaborated with James G. March on several works in organization theory.  With Allen Newell, Simon developed a theory for the simulation of human problem solving behavior using production rules. The study of human problem solving required new kinds of human measurements and, with Anders Ericsson, Simon developed the experimental technique of verbal protocol analysis. Simon was interested in the role of knowledge in expertise. He said that to become an expert on a topic required about ten years of experience and he and colleagues estimated that expertise was the result of learning roughly 50,000 chunks of information. A chess expert was said to have learned about 50,000 chunks or chess position patterns.  He was awarded the ACM Turing Award, along with Allen Newell, in 1975. "In joint scientific efforts extending over twenty years, initially in collaboration with J. C. (Cliff) Shaw at the RAND Corporation, and subsequentially [sic] with numerous faculty and student colleagues at Carnegie Mellon University, they have made basic contributions to artificial intelligence, the psychology of human cognition, and list processing."

Problem: Background: Charles Elwood "Chuck" Yeager (; born February 13, 1923) is a retired United States Air Force general officer, flying ace and record-setting test pilot. In 1947, he became the first pilot confirmed to have exceeded the speed of sound in level flight. Yeager's career began in World War II as a private in the United States Army Air Forces.
Context: Yeager was foremost a fighter pilot and held several squadron and wing commands. From May 1955 to July 1957 he commanded the F-86H Sabre-equipped 417th Fighter-Bomber Squadron (50th Fighter-Bomber Wing) at Hahn AB, Germany, and Toul-Rosieres Air Base, France; and from 1957 to 1960 the F-100D Super Sabre-equipped 1st Fighter Day Squadron (later, while still under Yeager's command, re-designated the 306th Tactical Fighter Squadron) at George Air Force Base, California, and Moron Air Base, Spain.  Now a full colonel in 1962, after completion of a year's studies at the Air War College, Yeager became the first commandant of the USAF Aerospace Research Pilot School, which produced astronauts for NASA and the USAF, after its redesignation from the USAF Flight Test Pilot School. (Yeager himself had only a high school education, so he was not eligible to become an astronaut like those he trained.) Between December 1963 and January 1964, Yeager completed five flights in the NASA M2-F1 lifting body. An accident during a December 1963 test flight in one of the school's NF-104s eventually put an end to his record attempts.  In 1966 Yeager took command of the 405th Tactical Fighter Wing at Clark Air Base, the Philippines, whose squadrons were deployed on rotational temporary duty (TDY) in South Vietnam and elsewhere in Southeast Asia. There he accrued another 414 hours of combat time in 127 missions, mostly in a Martin B-57 Canberra light bomber. In February 1968, Yeager was assigned command of the 4th Tactical Fighter Wing at Seymour Johnson Air Force Base, North Carolina, and led the McDonnell Douglas F-4 Phantom II wing in South Korea during the Pueblo crisis.  On June 22, 1969, Yeager was promoted to brigadier general and was assigned in July as the vice-commander of the Seventeenth Air Force.  From 1971 to 1973, at the behest of Ambassador Joe Farland, Yeager was assigned to Pakistan to advise the Pakistan Air Force. In one of the numerous raids carried out by Indian pilots against Pakistani airfields, Yeager's plane was destroyed while it was parked at Islamabad airport. Edward C. Ingraham, a U.S diplomat who had served as political counselor to Ambassador Farland in Islamabad recalled this incident in the Washington Monthly of October, 1985: "After Yeager's Beechcraft was destroyed during an Indian air raid, he raged to his cowering colleagues that the Indian pilot had been specifically instructed by Indira Gandhi to blast his plane. 'It was,' he later wrote, 'the Indian way of giving Uncle Sam the finger.'"
Question: Is there any other events that Yeager was involved with during his service?
Answer:
after completion of a year's studies at the Air War College, Yeager became the first commandant of the USAF Aerospace Research Pilot School,
