October 22

On the evening of October 28, 1995, a fire broke out aboard a passenger train in the underground tunnels of the Baku Metro. Dense smoke rapidly filled the carriage and tunnel, incapacitating riders and overwhelming rescue efforts; official authorities later reported 289 fatalities and hundreds injured. The disaster exposed technical faults and long-standing safety gaps in an aging Soviet-era transit system and prompted gradual, resource-constrained reforms.

On October 10, 1971, a scheduled Aeroflot passenger flight departed Moscow and, during its initial climb, suffered a sudden on‑board explosion that tore the airframe apart. The aircraft crashed near the capital, killing everyone aboard. Soviet investigators concluded that an explosive device detonated aboard, but public records identifying a perpetrator or motive remain limited.

On the night of October 10, 1997, Austral Líneas Aéreas Flight 2553, an MD‑83 operating from Posadas (with a stop in Resistencia) to Aeroparque Jorge Newbery in Buenos Aires, entered icing-laden clouds over the Uruguay River. Multiple airspeed indicators began to disagree; the autopilot disengaged; subsequent reductions in thrust and pitch changes led the aircraft into an aerodynamic stall from which it did not recover. The MD‑83 impacted near Nuevo Berlín close to Fray Bentos, Uruguay, killing all 74 people aboard. The accident prompted reviews of pitot‑static maintenance, crew procedures for unreliable airspeed, and simulator training across the region.
