Transport has always played an important role in people’s life. It’s a way of travelling from one place to another. Modern transportation system is rather well developed thanks to rapid scientific and technological progress. There are lots of busses, mini-vans, taxis, personal cars, bicycles, trains, airplanes, even ships and ferries in every developed country. However, a couple of centuries ago, there were only carts carried by horses and old-fashioned boats. Perhaps, the oldest type of transport is the water one. People constructed primitive boats for river navigation since the stone ages. The first land transport was presented by the carriages, which were later carried by domestic animals. The first animal-drawn vehicles were traced in Europe in the 4th millennium BC. Rail transport appeared much later, to be precise nearly 500 years ago. Modern railroad was introduced in the 19th century England. Aviation had several forms throughout the history. If we speak about the kites, they appeared in ancient China around before 200 BC. Then, there were the hot air balloons invented in the 18th century. The first aircraft flight was made by the Wright brothers at the very beginning of the 20th century. Perhaps, the discoveries made in the field of transportation in the 20th century were the most important. Thus, in 1961 the first human spaceflight was launched. In 1969, the first astronaut stepped on the Moon. Nobody knows exactly where else is scientific progress taking us, but it’s most likely that soon we will travel by spaceships more often
