Balkan Bulgarian Airlines Flight 107 was an accident that occurred on 16 March 1978, when a Tupolev Tu-134 operated by Balkan Bulgarian Airlines crashed on an international flight from Sofia Airport to Warsaw Airport. All 73 passengers and crew died in the crash (66 passengers and a crew of 7). As of 2024, it remains the deadliest accident in Bulgarian aviation history. The exact cause of the crash remains unknown.
A 2024 investigation by "Biograph" journal found witnesses in former communist Committee for State Security (DS) who testified that the aircraft had two unlisted passengers, who were most likely DS-trained agents from Arab countries. The aircraft was most likely hijacked in-flight and crashed as a result of onboard fighting, neither of which the communist government was ready to admit.
