The current use of turboprop and jet civil aircraft has a speed of 20 to 1 million meters and a continuous range of more than 10,000 kilometers. It is the fastest transportation in the world, and the aircraft is 20 to 30 times faster than the sea. 5 to 10 times faster than the train, 7 to 15 times faster than the car. As the times progress, the value of time increases.
Air shipping saves time by using aviation, and the social value created is difficult to estimate. Because the demand for air transportation is increasing in the modern society, the speed of air transportation is the highest among all modes of transportation.
Mobility, as long as there is an airport and necessary communication and navigation facilities between the two places, it can open up routes without being blocked by mountains, rivers, deserts and oceans. Therefore, the transportation distance is shorter than other modes of transportation.
