2–4 February 1982: Over a three-day period, several flight crews set a series of Fédération Aéronautique Internationale (FAI) payload-to-altitude world records at Podmoskovnoe. They flew an OKB Mil Design Bureau Mi-26 heavy lift helicopter.

On 4 February, Colonel Sergey V. Petrov and A. Chetverik lifted 15,000 kilograms (33,069.4 pounds) to 5,600 meters (18,373 feet).¹ On the same day, A. Kholoupov flew the helicopter to 4,600 meters (15,092 feet) with a payload of 20,000 kilograms(44,092.5 pounds).²

The eight-bladed main rotor has a diameter of 32.00 meters (105 feet) and turns clockwise, as seen from above. (The advancing blade is on the left.) A five-bladed tail rotor is mounted on a pylon, to the right side of the aircraft, in a tractor configuration. It turns clockwise, as seen from the helicopter’s left.
