From the Wikipedia article
The Mi-8 crash at Seyakha was an aviation accident that occurred on Saturday 17 November 1984 near the settlement of Seyakha (Yamalo-Nenets Autonomous Okrug) involving an Aeroflot Mi-8 helicopter, in which 15 people were killed.
Crash
The helicopter was performing a night passenger flight. On board were 3 crew members (aircraft commander A. A. Arutyunov) and 12 passengers — a delegation of Komsomol members from Seyakha, including schoolchildren, who were flying to the district Komsomol conference in Yar-Sale. The Mi-8 lifted off the ground and began to climb when suddenly, already at the 45th second, it went out of the pilots' control. Rolling over onto its right side and with its nose down, the helicopter crashed to the ground and broke up. All 15 people on board were killed. The cause of the loss of control was never established.
