On a cold December day, Aeroflot Flight 3519, a Tupolev Tu-154, took off from Krasnoyarsk International Airport bound for Sverdlovsk. Shortly after takeoff, the crew reported an engine fire and initiated emergency procedures to return to the airport. The flight was carrying 104 passengers and 7 crew members, totaling 111 individuals on board. As the aircraft circled back, it became evident that the situation was deteriorating. Despite efforts to land safely, the aircraft crashed just a few kilometers from the runway. The impact resulted in catastrophic damage and a high fatality rate. Only one passenger survived the crash due to the quick response of emergency services. This incident exposed the inherent risks associated with aviation during that era, particularly concerning the aging fleets of aircraft in operation. The Soviet Union's aviation industry was navigating through significant challenges, ranging from maintenance issues to the rigorous demands of a growing passenger transport network. Investigations into the crash sought to identify causes related to pilot error, mechanical failure, and the safety protocols of the time. This accident is noted in aviation history for the tragic loss of life and the lessons learned regarding aircraft safety.
