The pictures illustrate how airplanes evolved since their invention. It is clear from the diagrams that over a period of more than a century, aeroplanes' dimensions, the number of passengers they can carry and their speed increased considerably.
Starting with Wright Flyer invented in 1903, we can see that it had a basic design with a propeller and measuring 6m in length and having a 12-meter wingspan. This original airplane prototype, with a maximum speed of 16km/h, could carry only one person, a pilot.
In 1935, a more developed Douglas DC-3 was invented. As opposed to the first model, it had engines and was long enough to serve 28 passengers as well as 3 crewmembers. Although this model's dimensions were slightly larger, its speed was significantly faster: 347km/h.
The latest and the most advanced airplane shown had been created by 2004. Called Airbus A380, it could speed up to 1050km/h and transport 555 passengers at a time. Unlike the former two aircraft, interestingly, this version had a longer wingspread (80m) than the overall length (73m).
