The Boeing 767 became the most frequently used airliner for North America and Europe transatlantic flights.
 The mid-size 757 and 767 launched to market success, due in part to 1980s extended-range twin-engine operational performance standards (ETOPS) regulations governing transoceanic twinjet operations
 By the 1960s, airliners had expanded capabilities, making a significant impact on global society, economics, and politics
