About the 707-320:

Introduced in 1957, the Boeing 707-320 is a significant aircraft in the history of commercial aviation, marking Boeing's venture into the jetliner market. As a narrow-body, long-range airliner, the 707-320 played a pivotal role in the jet age, revolutionizing air travel with its speed and range capabilities.

The 707-329 is 46.6 meters (152.9 feet) long, and 44.4 meters (145.7 feet) from wing tip to wing tip, making it one of the larger aircraft of its time. Its design accommodates a typical seating arrangement for 137 passengers. Equipped with four engines, the 707-320 delivers a total thrust of 340.0 kN (76,000 lbf). Its fuel capacity of 90,300 liters (23,855 US gallons) contributes to a range of 5,400 kilometers (2,916 nautical miles). With a cruise speed of 890 km/h (553 mph), the 707-320 was known for reducing travel times significantly compared to propeller-driven aircraft, making it popular for transatlantic routes. Its cockpit required three crew members: a pilot, copilot, and flight engineer.

In the commercial aviation sector, the Boeing 707-320 competed with aircraft like the Douglas DC-8. Its introduction was a major step forward for Boeing, establishing the company as a leader in the jetliner market. The 707-320's ability to cover long distances quickly and efficiently made it a preferred choice for airlines expanding their international operations. Airlines such as Pan American World Airways, TWA, and Lufthansa operated the Boeing 707-320, utilizing its capabilities to offer faster, more comfortable international flights. The aircraft's role in expanding the global reach of air travel was significant, contributing to the growth of the airline industry and the accessibility of air travel.
