Boeing 707

The Boeing 707 is an American four-engine jet airliner developed by Boeing. Its introduction into airline service in 1958 helped establish long-distance commercial jet travel.

Swept wing: An aircraft wing angled backward from its root to reduce drag near the speed of sound. The 707's swept wings helped it cruise efficiently at high subsonic speeds.
Boeing 367-80: Boeing's prototype jet aircraft, built to demonstrate a design that led to the 707 and KC-135. Its 1954 first flight demonstrated the design from which Boeing developed the airliner.
Pan American World Airways: An American international airline that pioneered long-distance passenger routes and operated the first scheduled 707 service. Pan Am introduced the 707 on scheduled transatlantic service in October 1958.
Convair 880: A fast, narrow-body American jet airliner produced by Convair in the late 1950s and 1960s. Convair pursued speed and smaller capacity against the 707's broader market position.
Jet airliner: A passenger aircraft powered by jet engines and designed for scheduled airline service. The 707 became a defining early example of the commercial jet airliner.
Pratt & Whitney JT3C: A turbojet engine used on early Boeing 707 variants. The JT3C powered the first production 707s before later models adopted turbofans.
Boeing KC-135 Stratotanker: A four-engine jet tanker developed by Boeing from the same basic design as the 707. The military tanker contract helped finance and shape the 707's prototype lineage.
Qantas: Australia's national airline, founded in 1920 and a major international carrier. Qantas used 707s to expand long-haul service from Australia.
de Havilland Comet: The first commercial jet airliner to enter scheduled service, introduced by Britain's de Havilland in 1952. The Comet pioneered airline jet travel before the 707 brought it to wider adoption.
Commercial jet age: The period when jet aircraft became the dominant form of long-distance commercial air travel. The 707 helped make this transition widespread in the late 1950s and 1960s.
