The biggest airplane in the world is the Antonov 225. It was originally design to transport space shuttles in 1988. It has a length of 84 meters, a body of 88,4 and its height is 18,1 meters. It seems almost impossible that such a giant can take off.
This airplane is also one of a kind, they did not produce any more of them. This aircraft has shown that is capable of attracting the press and generating a huge expectation wherever it lands.
