The Jet Engine and Leisure Air Travel
Air transport for European tourists got off to a shaky start in the late 1920s.But it was to be thirty years before leisure air travel was to appeal to anyone but the rich and adventurous. High cost, fear of flying and the absence of toilets in early airliners (an unfortunate combination) were the main deterrents; the unpressurized aircraft of the inter-war years were noisy, slow and not especially comfortable despite the efforts of some airlines to make aircraft cabins resemble the first-class state- rooms of an ocean liner. This changed fundamentally after 1958: with the introduction into airline service of the Boeing 707, the Douglas DC-8 and the de Havilland Comet 4, aircraft were capable of flying fast, high and with hitherto unknown smoothness. The jet age had arrived. This paper considers this “age” and its impact on tourism in the 1960s and 1970s. It argues that while the revolution in
European leisure air travel that took place in these years was obviously the result of social and economic change (more disposable income, a greater propensity to take foreign holidays and the entry of new capital into the independent airline industry), there was also a critical additional factor. This was the breakthrough in transport technology represented by the jet engine and it is on this aeronautical artifact that the paper’s main focus will lie.

Technological change was crucial to the process of economic and social modernisation in both the 19 th and 20 th centuries. New technologies of power generation, manufacturing, transport and communications changed the world and shrunk time and space. What is generally termed “Fordism” grew out of the mass production of automobiles to encompass a whole array of practices and institutions that now underpin modern Western society

Fordist lifestyle of mass consumption set in after 1950 and this included the international tourist industry, the single largest and fastest-growing industry in the world

The technological change that triggered and accompanied this explosion in tourist activity was the introduction of the jet engine. Indeed the jet engine has been as vital a part of social modernisation as mass tourism itself. The jet engine’s evolution and dominance in aerospace propulsion since 1950 is traditionally described in terms of the transfer of technology from military to civilian usage: the turbo- jet grew out of the Second World War and the preparation for it, and was later installed in civil
Growth of commercial aviation was greatly influenced when the U.S. Air Mail Service was created in the early 1920’s. The Post Office was one of the first to impose aviation regulations. It required its pilots to be tested, pass medical exams and have at least 500 hours of flying experience. The Post Office set up aircraft inspection schedules and preventive maintenance programs for the pilots to have a safe airplane to fly. These early regulatory requirements improved air carrier safety.
One of the most common expenses was corporate airplanes. Such travel arrangements cost many fold compared to a commercial airline. The cost per hour would be close $5000. Moreover, these aircrafts would not carry any other passengers except for the corporate managers and would take them to their destination and fly them back. This put the entire cost of the aircraft on

In a series of experiments conducted from 1960 to 1963, American psychologist Stanley Milgram, sought to examine the relationship between obedience and authority in order to understand how Nazi doctors were able to carry out experiments on prisoners during WWII. While there are several theories about Milgram’s results, philosopher Ruwen Ogien uses the experiment as grounds for criticizing virtue ethics as a moral theory. In chapter 9 of Human Kindness and The Smell of Warm Croissant, Ogien claims that “what determines behavior is not character but other factors tied to situation” (Ogien 120). The purpose of this essay is not to interpret the results of the Milgram experiments. Instead this essay serves to argue why I am not persuaded by Ogien’s
In 1978, deregulation removed government control over fares and domestic routes. A slew of new entrants entered the market, but within 10 years, all but one airline (America West), had failed and ceased to exist. With long-term growth estimates of 4 percent for air travel, it's attractive for new firms to service the demand. It was as simple as having enough capital to lease a plane and passengers willing to pay for a seat on the plane. In recent news, the story about an 18-yr British...
After September 11th, 2001, the airline industry experienced a significant drop in travel. The reasons for the airline industry downfalls also included a weak U.S and global economy, a tremendous increase in fuel costs, fears of terrorist's attacks, and a decrease in both business and vacation travel.
Nightingale, F. (1898). Notes on nursing: what it is and what it is not. New York, NY:
One of which is person “the recipient of nursing care” (Finkleman & Kenner, 2013, p. 28). I feel two of Nightingale’s canons are based on the patient petty management and personal cleanliness. Environment is the second concept which Nightingale explains “the external and internal environment” of the patient (Finkleman & Kenner, 2013, p. 29). I believe nine of Nightingales canons are aimed towards this concept ventilation and warmth, health of the house, noise, variety, food intake, food, bed and bedding, light, and cleanliness of room and walls. Nursing is the third concept which Nightingale believes they “alter or manage the environment to implement the natural laws of health” (Finkleman & Kenner, 2013, p. 28). I feel the two canons chattering hopes and advice, and observation of the sick best explains this concept. Lastly, the concept of Health, Nightingale believed that health is not only the absence of disease but being able to utilize everything that we are. I believe that the previous three concepts must be fulfilled to achieve the last and final concept because the patient is effected by the environment and the
Following World War II and the jet engine technology that emerged largely toward its end, aerospace engineers knew well that the technology had great potential for use in the commercial aviation industry. The Comet was the first aircraft to utilize jet propulsion; however, its designers failed to consider the metallurgy of the aircraft’s materials under flight conditions or the consequences of their atypical window design. The aircraft was designed by Britain’s De Havilland Aircraft Company and entered service in May 1952. After a year of service, however, the design issues mentioned above resulted in the failure of several Comet aircraft. Extensive evaluations revealed that repeated pressurization stress on the aircraft’s main cabin had caused its structure to fail.
Few things escaped the shadow cast by World War II, and the aviation industry was no exception. For 60 wearisome months, United put aside its quest for growth and
The airline industry has long attempted to segment the air travel market in order to effectively target its constituents. The classic airline model consists of First Class, Business Class and Economy, and the demographics that make up the classes have both similarities and differences to the other classes. For instance, there may be similarities between business class travellers on a particular flight, but they will not all be travelling for the same reason. An almost-universal characteristic of air travel is that customers do not fly for the sake of flying; the destination is the important element and the travel is a by-product, a means-to-an-end that involves the necessity of an aircraft that gets the customer from point A to point B. Because the reasons can differ greatly in the motivations for a customer wanting to fly, it can be difficult to divide the market into discrete segments, that is, there is always going to be overlap in the preferences and characteristics of any given segment. With that in mind, the commonalities that are shared between the clientele that make up the respective classes can easily withstand analysis.

Aviation was big during the 1920’s. The first airplanes that were developed were made of wood and canvas, they were later modernized and than made of an increasing amount of metal during this era. Airplanes were typically only used to carrying heavy loads and for wars, but during this era they were able to start taking passengers as well. It was only in 1927 that an airport terminal in the form of a waiting room and ticket-office for airplane passenger...
From the dawn of time, man has followed his urge to travel; sometimes neglecting the enjoyment of the journey in pursuit of the destination. Although two of the favorable means of passenger transportation - the plane and the train - accomplish the task of arriving at a destination, there are distinct differences in their capacity for comfort, time, scenic value, and safety.
arduous travel by land and sea. It was no unexpected that they never return. Travel during those days was filled with danger. Today we take travelling far distances for granted. The risks are negligible. People are more concerned about whether they travel first-class or economy.
