On 24 February 1996 a Cuban Air Force Mikoyan MiG-29UB shot down two unarmed Cessna 337 Skymaster aircraft operated by Brothers to the Rescue, an organization opposed to the Cuban government. The Organisation of American States (OAS) reported that no warning was given; Cuban government sources said "These people knew what they were doing. They were warned", and that the aircraft had entered Cuban airspace. All the occupants of the aircraft were killed: Carlos Costa, Armando Alejandre, Jr., Mario de la Peña, and Pablo Morales. A third Cessna involved escaped. Previous similar flights had released propaganda leaflets over Cuba.
