America entered the era of jet transportation on July 15, 1954, when the Boeing Dash 80 prototype for both the KC-135 military tanker and the Model 707 commercial jet transport made its maiden flight from Renton Field, south of Seattle, Wash. The 144-foot-long Model 707 followed the KC-135 into production. On Oct. 26, 1958, Pan American World Airways inaugurated transatlantic 707 jet service between New York and Paris. Boeing custom-designed the 707s to meet a variety of airline requirements, including the 9-foot-shorter 720 for short to medium routes. The long-range 707-320 Intercontinental transport was most ordered and also was modified to become the first Air Force One presidential aircraft, as well as for the E-3 Airborne Warning and Control System (AWACS) and the E-6 submarine communications system.
