Designed by the Soviet Union's Antonov Design Bureau in the 1980s, the Antonov An-225 Mriya is touted as the world's largest, longest and heaviest aircraft.

The An-225 has since become the workhorse of the Antonov Airlines fleet, transporting objects once thought impossible to move by air, such as locomotives and 150-ton generators. It has become an asset to international relief organizations for its ability to quickly transport huge quantities of emergency supplies during disaster relief operations.
