Aeroflot Flight 217

Aeroflot Flight 217 was a non-scheduled international passenger flight from Orly Airport in Paris to Sheremetyevo International Airport in Moscow, with a stopover at Shosseynaya Airport (now Pulkovo Airport) in Leningrad (now Saint Petersburg). 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. At the time, it was the world's deadliest civil aviation disaster, until it was surpassed by the Kano air disaster in 1973. , this remains the second-deadliest accident involving an Il-62, after LOT Flight 5055, and the second-deadliest on Russian soil, after Aeroflot Flight 3352.

Crash
Shortly before the expected landing, the plane was flying at the altitude of 1200 m and received the ATC instructions to descend to 400 m. The crew confirmed and started to descend, but later there was no action to return to the horizontal flight. The plane passed the 400 m mark with 20 m/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.

Investigation
The cause of the crash could not be determined. Investigators did believe the most probable cause was the 'psycho-physiological incapacitation of the crew for reasons unknown'. Somewhere around 500 - 600 m altitude, 30–25 seconds before impact, the pilots either have been incapacitated or lost control of the plane.
