|History of technology|
Jet airliners were able to fly much higher, faster, and farther than older piston‑powered propliners, making transcontinental and intercontinental travel considerably faster and easier: for example, aircraft leaving North America and crossing the Atlantic Ocean (and later, the Pacific Ocean) could now fly to their destinations non-stop, making much of the world accessible within a single day's travel for the first time. Since large jetliners could also carry more passengers than piston-powered airliners, air fares also declined (relative to inflation), so people from a greater range of socioeconomic classes could afford to travel outside their own countries.
Besides the pure jet, the turbine driven propeller engines offered improvements of the piston engine delivering a smoother ride and better fuel efficiency. One exception to jet-powered domination by large airliners was the contra-rotating propellers turboprop design that powered the Tu-114 (first flight 1957). This airliner was able to match or even exceed the speed, capacity and range of contemporary jets; however, the use of such powerplants in large airframes was totally restricted to the military after 1976.
The introduction of the Concorde supersonic transport (SST) airliner to regular service in 1976 was expected to bring similar social changes, but the aircraft never found commercial success. After two and a half decades of service, a fatal crash near Paris in July 2000 and other factors eventually caused Concorde flights to be discontinued in 2003. This was the only loss of an SST in civilian service. Only one other SST design was used in a civilian capacity, the Soviet era Tu-144, but it was soon withdrawn due to high maintenance and other issues. McDonnell Douglas, Lockheed and Boeing were three U.S. manufacturers that had originally planned to develop various SST designs since the 1960s, but these projects were eventually abandoned for various developmental, cost, and other practical reasons.
The term "Jet Age" was coined in the late 1940s. At the time, the only jet-powered aircraft in production were military types, most of which were fighters. The expression reflects the recognition that the jet engine had effected, or would soon, a profound change in aeronautics and aviation.
One view is that the jet age began with the invention of the jet engine in the 1930s and 1940s. In the history of military aviation it began in 1944 with the introduction into service of the Arado Ar 234 reconnaissance bomber and the Messerschmitt Me 262 fighter during World War II. In commercial aviation the jet age was introduced to Britain in 1952 with the first scheduled flight of the de Havilland Comet airliner and to America later in the decade with the first American-built jet airliners.
The British de Havilland Comet was the first jet airliner to fly (1949), the first in service (1952), and the first to offer a regular transatlantic service (1958). One hundred and fourteen of all versions were built. However, the first jet airliner to provide a sustained and dependable service was the Soviet Tupolev Tu-104 (201 built) which was the only jet airliner in operation worldwide between 1956 and 1958 (the Comet having been withdrawn in 1954 due to structural failure issues). The Comet and Tu-104 were later outstripped in production by the American Boeing 707 (which entered service in 1958) and Douglas DC-8, which joined it in the skies over the next few years. Other types of the period included the French Sud Aviation Caravelle. When the 707 began service on the New York to London route in 1958, this became the first year that more trans-Atlantic passengers traveled by air than by ship.
As the number of passengers soared, it became impractical to increase the number of aircraft flying from the major hub airports. International airports like that of Orly Airport in Paris, France would construct terminals around bag-check and customs processing efficiency in response to rising passenger numbers. Instead, designers created even larger widebody airliners and the engine manufacturers responded with larger, more powerful and also more fuel-efficient engines. The first "jumbo jet" was the Boeing 747, and it both increased airport passenger capacity and reduced the cost of air travel, further accelerating the social changes brought about by the Jet Age.
Military aviation had entered the jet age somewhat earlier, during the closing stages of World War II. In the early postwar years, the increasing use of jet aircraft had little significant impact, serving mainly to continue the slow but steady improvements in performance seen in the past. Supersonic flight brought about a step change in aircraft performance. The Bell X-1, first to break the sound barrier in level flight, was an experimental rocket-powered type, and production jets which followed it into service could fly little faster. The first jet aircraft designed from the outset for supersonic flight was the British Fairey Delta 2. On March 10, 1956 it became the first aircraft to fly faster than 1,000 miles per hour, heralding an era of "fast jets" typically limited to a speed of Mach 2.2 by the engineering materials available. As jets became faster, their armament changed from guns to missiles. Avionics systems became more complex with radar, fire-control and other systems. Aircraft became larger and more expensive, and so were required to do more to make them economical. All this profoundly affected the nature of military strategy during the Cold War.
Impact on Hollywood and entertainment
In 1958, the year of the 707's introduction, Frank Sinatra sang the popular song Come Fly with Me and was a major hit for him. In 1965, Paramount Pictures released the movie Boeing Boeing about two bachelors who lived in Paris who shared a bachelor pad where they dated stewardesses who are assigned to international routes on non-intersecting flight schedules so that only one is in the country at any given time.
