The deadliest event the Soviet Union's flag carrier went through in the decade occurred in November 1967 (1967-11), when an Ilyushin Il-18V crashed upside down shortly after takeoff from Koltsovo Airport in Sverdlovsk, then located in the Russian SSR, killing all 107 occupants on board,[1] prompting the temporary grounding of the type within the airline's fleet.
In terms of fatalities, the accident ranks as the fifth worst involving an Il-18, as of April 2016[update].
The decade was also marked by the only deadly accident experienced by a Tupolev Tu-114, which entered commercial service on the Moscow–Khabarovsk route in April 1961 (1961-04).
Certain Western media conjectured that the Soviet government was reluctant to publicly admit the occurrence of such events, which might render these figures higher, as fatal events would have only been admitted when there were foreigners aboard the crashed aircraft, the accident took place in a foreign country, or they reached the news for some reason.
[5] However, no significant amount of unreported serious accidents have emerged after the dissolution of the USSR, in any of its then-constituent republics.
