do you agree or disagree that the automobile has had greater effect to society than the airplane do An increasing number of people are joining the "global-village" via the advanced communication as well as transportation. It is hard for the old generation to imagine such convenient tools like automobiles and aircrafts in the past because they use to take boat instead, which is a kind of marine steam-powered vehicle. However, the development of the fast transportation affords people the sense of belonging due to the ability of long way travel. But if asked about which one contributes much to our society, the answer is clear--airplane. When we are in this cosmopolitan world with lots of international activities, the most essential ingredient of the vehicle is definitely the transport distance. It equip us with the ability to touch every pieces of land on the earth in less than 24 hours. Many businessmen will have demand of ashuttle back and forth trough countries for their international trade and the time gives them a competitive edge. Same as the political men who had to attend plenty of conferences around the world, the airplane is a much faster and safer choices compared with cars. Another main element that people pay attention to is the safety problem. It is funny that some people drive across the country with unbelievable expensive gas fee just because they think that terrestrial vehicles are dependable with little accident. However, they are totally wrong about this. In fact, on the other hand, airplane is much safer than cars and reasons are apparent. Aircrafts must be sent to the special institution and every part of it will be disconnect to test the whether the function still normal twice a year, which in addition provide lots of jobs towards society. Automobiles' condition seems worse contrast to the former. I use to hear some news reported than drivers who sent tester gifts or money in order to pass the test because cars are in bad repair. If these cannot convince you, let me show you the date of the survey according to the NAS(national accident statistics). The percentage of the risk of car accidents is about 7 percent, in the country, the aircrafts' accident risk is only about 0.32 percent. That obviously shows the difference. We do choose to drive when the distance is not too long and it is more convenient than air plane because the process of getting aboard is time-consuming. The situation has already changed nowadays owing to the politics and the development of the full-automatic inspect, which enables us finish the security check.
