At the funeral, former president George W. Bush eulogized his father saying, Bush flew his first combat mission in May 1944, bombing Japanese-held Wake Island, and was promoted to lieutenant (junior grade) on August 1, 1944. Following the end of World War II, Bush enrolled at Yale University, where he took part in an accelerated program that enabled him to graduate in two and a half years rather than the usual four. He was a member of the Delta Kappa Epsilon fraternity and was elected its president.
