Destruction of Avianca Flight 203

Date: November 27, 1989 • Location: Soacha, Colombia

A bomb placed by the Medellín Cartel in an attempt to kill Colombian presidential candidate César Gaviria destroyed Avianca Flight 203, killing all 107 people on board, excluding Gaviria, who was not on the flight.

The Medellín Cartel was a confederation of Colombian drug trafficking organizations based primarily in Medellín, Colombia, that played a central role in the expansion of the international cocaine trade during the late 1970s and 1980s. Rather than a single hierarchical organization, contemporary law-enforcement assessments and subsequent scholarship describe the cartel as a network of semi-autonomous traffickers who cooperated in production, transportation, financing, and enforcement while retaining independent control over their respective operations. The network included prominent traffickers such as Pablo Escobar, Carlos Lehder, Gonzalo Rodríguez Gacha, and the Ochoa brothers—Jorge Luis Ochoa Vásquez, Fabio Ochoa Vásquez, and Juan David Ochoa Vásquez—whose activities collectively shaped the structure and scale of Colombian cocaine trafficking during this period. Estimates by U.S. and Colombian authorities during the 1980s attributed a substantial share of cocaine entering the United States to trafficking networks associated with Medellín, though contemporaneous reports emphasized that market share fluctuated over time and could not be ascribed to a single unified organization.
