On 13 October 1972, the Ilyushin Il-62 airliner operating the flight crashed on approach to Sheremetyevo, with the loss of all 164 passengers and crew of 10.
The crew confirmed and started to descend, but later there was no action to return to the horizontal flight.
The plane passed the 400-metre (1,300 ft) mark with 20 m/s (66 ft/s) vertical velocity, no expected report to ATC and engines still running at low thrust.
It crashed shortly afterwards, with landing gear up, spoilers retracted and horizontal speed about 620 km/h (330 kn; 390 mph).
[6] Somewhere around 500–600 metres (1,600–2,000 ft) altitude, 30–25 seconds before impact, the pilots either had been incapacitated or lost control of the plane.
