Here is an example of a transportation history timeline. From the 1950s to the 2000s, there were many significant things happened in transportation. In the 1950s, the double-rotor helicopter was invented in Germany. Then the hovercraft was invented in England. The first commercial high-speed Maglev train started operation between Shanghai and its airport. Timelines are often used in history recording and biographies. Besides, project management always needs to use timelines. Timelines capture the essence of what the team is going to do and how it is going to be accomplished.
