input: As the eldest daughter of Edward IV with no surviving brothers, Elizabeth of York had a strong claim to the throne in her own right, but she did not assume the throne as queen regnant. Such a precedent would not truly come to England for another 67 years, when her granddaughter, Mary I, acceded to the throne. Though initially reluctant to keep his promise Henry VII acknowledged the necessity of marrying Elizabeth of York to ensure the stability of his rule and weaken the claims of other surviving members of the House of York, but he ruled in his own right and claimed the throne by right of conquest and not by his marriage to the heir of the House of York. He had no intention of sharing power. He consequently chose to be crowned on 30 October 1485 before his marriage.  Henry VII had the Titulus Regius repealed, thereby legitimising the children of Edward IV, and acknowledged Edward V as his predecessor. After procuring papal dispensation, Cardinal Bourchier, Archbishop of Canterbury, officiated at the wedding of Henry VII and Elizabeth of York on 18 January 1486 in Westminster Abbey. Their first son, Arthur, was born on 20 September 1486. Elizabeth of York was crowned queen on 25 November 1487. Following her coronation, she gave birth to seven more children, but only four survived infancy: Arthur, Margaret, Henry and Mary.  Despite being a political arrangement at first, the marriage proved successful and both partners appear to have grown to love each other. Elizabeth of York did not exercise much political influence as queen due to her strong-minded mother-in-law Lady Margaret Beaufort, but she was reported to be gentle, kind, and generous to her relations, servants, and benefactors. When not at official gatherings, she lived a quiet life largely away from politics with three of her children at Eltham Palace. Elizabeth of York enjoyed music and dancing as well as dicing. She also kept greyhounds.  On 14 November 1501, Elizabeth of York's 15-year-old son Arthur married Catherine of Aragon, daughter of King Ferdinand II of Aragon and Queen Isabella I of Castile. The pair were sent to Ludlow Castle, the traditional residence of the prince of Wales. Arthur died in April 1502. The news of Arthur's death caused Henry VII to break down in grief, as much in fear for his dynasty as in mourning for his son. Elizabeth comforted him, telling him that he was the only child of his mother but had survived to become king, that God had left him with a son and two daughters, and that they were both young enough to have more children.

Question: 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.

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.'"
