       A timeline can help us figure out the history of transportation and shows its developed through early times, to the Middle Ages and the modern ages from 3500BC to the present .In pre-historic ages man learned to live in groups and traveled extensively in search of food and shelter. This involved walking and swimming .However, gradually man learned to use animals to carry himself as well as his belongings. Use of animals as means of transportation was revolutionized by the invention of the wheel. This can be given the credit for changing the whole concept of traveling. The first movement of wheeled vehicles was in 3500BC in Mesopotamia as carts allowed people to move easily. In the same year, the Egyptians and the Mesopotamians invented river boats using wood or reeds. In 2000BC the Egyptians created a new ship built using panels. Later on, engineers working for Alexander the Great invented submersible crafts in 332 BC.     

During the middle Ages, there was more development. Between 181- 234 Chuko Liang created the wheelbarrow and in the 13^th century the rocket was also invented by the Chinese.    The development of transportation has expanded greatly after the 17^th century.  In 1662 Blaise Pascal invented a bus for public transport and in 1672 the power car was invented by Ferdinard Verbint. In 1801 Richard Trevithick created the first steam train and Lenoir invented a gasoline powered car. In 1903 the airplane was invented by Wright brothers, while helicopters arrived in 1940, invented by Cornu. Then in 1975 Sputrik invented the first satellite and space became accessible.   (Chaitra Suraj Saxena).
