Avianca Flight 9463
Avianca Flight 9463 was a scheduled domestic passenger flight from Bucaramanga to Bogotá in Colombia. On April 12, 1999, a Fokker 50 operating the route was hijacked by a command of six guerrillas from the National Liberation Army (ELN). The aircraft was carrying 41 passengers and five crew members. Hijacking 
Avianca flight 9463 was operating a route between the cities of Bucaramanga and Bogotá when at approximately 10:30 AM seven armed men rose out of their seats and identified themselves as members of the National Liberation Army (ELN). The Colombian authorities became aware of the hijacking at around 12:30 noon. The hijackers demanded that the passengers assume the emergency brace position and not lift their heads. Once the cabin was under control, one of the hijackers entered the cockpit with a gun, and forced the captain of the aircraft out of the cockpit. The hijacker then forced the first officer to divert the aircraft to a clandestine landing strip called “Los Sábalos”, located in the village of El Piñal, district of Vijagual, between the municipalities of Simití and San Pablo in the south of the department of Bolívar. Once on the ground, the hijackers got off the plane and proceeded to wait next to the aircraft, while another group of ELN guerrillas from the "Heroes de Santa Rosa" group took the passengers and crew off the aircraft, among the passengers was a baby and several elderly people. They proceeded to take the passengers of the aircraft into the surrounding jungle and subsequently floated them down a river where after they were transferred to a camp where they remained until their release. Releases 
One day after the hijacking, the ELN hijackers released the baby and five elderly people thanks to negotiations with Red Cross delegate, Ernesto Herrera Calderon. On April 15, 1999, the hijackers released three more people who had health conditions also thanks to the same delegate. On May 7, four more people were released, also thanks to Ernesto Herrera Calderon, who acted as a facilitator and neutral intermediary during the negotiations for releases. Hostages were being released gradually until November 22, 2000, on which the last hostage, Gloria Amaya de Alfonso, was released. During the ordeal, one person died: Carlos Gustavo González. The organisation of their release was initially managed by journalist and comedian Jaime Garzón who had previously been a mediator for the release of 100 people kidnapped by the FARC-EP a year earlier. Garzón, would meet with leaders of the ELN in the Itagüí prison to expedite the release of the hostages, but these mediations were cut short, since the journalist was killed by paramilitaries accusing him of trying to profit off the hostages, as well as other incidents. Court Proceedings 
The Supreme Court of Justice of Colombia ratified the decision of the Second Criminal Court of the Bucaramanga Circuit of May 16, 2005. The sentence condemned the hijackers, Luis Eduardo Galvis Rivera, William Ricardo Blanco Suárez and Héctor Dante Becerra Salazar to 37, 36 and 36 years in prison, respectively, for the crimes of aggravated extortive kidnapping, seizure and diversion of aircraft, material falsehood in public documents and destruction, suppression and concealment of public documents.
