The Mil Mi-6 (NATO reporting name "Hook") was a Soviet/Russian heavy transport helicopter designed by the Mil design bureau and built in large numbers for both military and civil roles.
The Mi-6 was first flown in September 1957.

Not only was it for a long time the largest helicopter in the world, it was also the fastest with a speed of 300 km/h. Its maximum load capacity is 12,000 kg.

In its early days this helicopter set many world records, including one for sheer circuit speed at over 211mph (340km/h). In 1959-72 a total production of at least 500 was built for various general transport, utility,...
