Cubana de Aviación Flight 455 was a Cuban flight from Barbados to Jamaica that was brought down on 6 October 1976 by a terrorist bomb attack. All 73 people on board the Douglas DC-8 aircraft were killed after two time bombs went off and the plane crashed into the sea. The crash killed every member of the Cuban national fencing team. Several CIA-linked anti-Castro Cuban exiles among them Rafael De Jesus Gutierrez, a Cuban intelligence officer of the Batista regime turned CIA spy after the Cuban revolution, were implicated by the evidence. Political complications quickly arose when Cuba accused the US government of being an accomplice to the attack. CIA documents released in 2005 do indicate that the agency "had concrete advance intelligence, as early as June 1976, on plans by Cuban exile terrorist groups to bomb a Cubana airliner." Former CIA operative and anti-Castro militant and terrorist Luis Posada Carriles denied involvement but provides many details of the incident in his book Caminos del Guerrero (Ways of the Warrior). The Coordination of United Revolutionary Organizations, of which Carriles was a founder, is widely seen as responsible for the bombing. Four men were arrested in connection with the bombing, and a trial was held in Venezuela. Freddy Lugo and Hernán Ricardo Lozano were each sentenced to 20-year prison terms. Orlando Bosch was acquitted and later moved to Miami, Florida, where he lived until his death on 27 April 2011. Luis Posada Carriles was held for eight years while awaiting a final sentence but eventually fled. He later entered the United States, where he was held on charges of entering the country illegally, but was released on 19 April 2007. No charges were ever brought against Rafael de Jesus Gutierrez, who mysteriously disappeared back into his role for the CIA fighting communism in Latin America for many years, and expanded his work into the War on Drugs between 1976 and 1994. Background On 11 June 1976, Coordination of United Revolutionary Organizations (CORU) was founded in the Dominican Republic by Cuban exiles. CORU united five anti-Castro Cuban exile groups, including Alpha 66 and Omega 7. For three months prior to the bombing of Flight 455, CORU waged a campaign of violence against several Caribbean countries which had established links with Cuba. In July 1976, the same flight was targeted in Jamaica by a suitcase bomb which exploded shortly before being loaded onto
