Investigation Summary
The sabotage of Flight 455 was carried out using two explosive devices, reportedly C4 plastic explosives. The first bomb detonated in the rear of the cabin, and a second exploded in the aircraft's lavatory. These blasts initiated a massive fire and filled the cabin with toxic gases. The flight crew, led by Captain Wilfredo Pérez Pérez, immediately declared an emergency and attempted to return to Seawell Airport. However, the fire damaged critical control systems. Witnesses and radar data indicated the aircraft lost altitude rapidly. In a final act of airmanship, the pilots banked the aircraft away from populated beaches toward the open sea before it impacted the water in a nose-down, wing-low attitude.
Final Conclusions
The Barbados Commission of Enquiry concluded the probable cause was the detonation of explosive devices which initiated an uncontrollable fire and produced toxic gases, eventually incapacitating the pilots. The investigation and subsequent legal proceedings in Venezuela identified Freddy Lugo and Hernán Ricardo Lozano as the individuals who placed the bombs, acting under the direction of Luis Posada Carriles and Orlando Bosch. The event remains one of the deadliest acts of air terrorism in the Western Hemisphere.
