During World War II, Boeing produced a large number of bombers. In the mid-1950s, technology advanced significantly, enabling Boeing to develop and produce entirely new products. One of the new products was the short-range guided missile used to intercept enemy aircraft. As the Cold War became routine, Boeing used short-range missile technology to develop and produce intercontinental ballistic missiles. In 1967, Boeing introduced a short-to-medium-range passenger aircraft with two B737 engines. It became the best-selling jet airliner in civil aviation history.
