I believe that one of the most importan development in transportation has been the development of international jet transport. Since this style of transportation appeared in the 1950s,it has had some revolutionary effects. Because of the high speeds and the relatively low costs of this type of travel,it has changed the way people look at the world.

The most obviously important characteristic of jet travel is the high speed involved. A hundred years ago, it took weeks to cross the Atlantic or Pacific Oceans by ship. Today, those ame trips can be completed in a matter of hours.One can attend a meeting in Paris and have dinner in New York the same day.These amazing speeds have changed people’s concepts of space.Today the world is much smaller than it was in the past.

Another important aspect of jet travel is its relatively low cost. An interenational journey one hundred years ago was extremely expensive. Only wealthy people could afford to travel comfortably, in first class .Poor people had to save for years to purchase a ticket, and the conditions in which they travel were not very good. Today it is possible for more and more people in every country to travel in comfort.

Thus it is possible for businessman to do business all over the world, for students to attend universities in other countries, and for toutists to take vacations anywhere in the world.

In conclusion, the speed and low cost of international jet travel have changed the world. Individual nations are not as isolated as they were in the past, and people now think of the whole planet as they once thought of their own hometowns。
