Report

Investigation Summary

On August 9, 1974, Buffalo 461 was performing a scheduled logistics flight between Ismailia, Egypt, and Damascus, Syria, with a stopover in Beirut. To avoid Israeli airspace, the flight followed a convoluted route over the Mediterranean before turning inland toward Damascus. The aircraft was painted in high-visibility United Nations white and blue livery and was operating under an ICAO flight plan. At 12:46 p.m. local time, the crew reported their position over the Dakweh Beacon in Lebanon. Damascus Air Traffic Control cleared the flight to the Damascus VOR to maintain 8,000 feet and cross 'Mike Echo Zulu' at 10,000 feet or above. However, the aircraft was reportedly at 11,000 feet when it was targeted by a Syrian missile battery located at an airfield approximately 14 miles from the Lebanese border. A witness on the ground reported seeing three separate missile engagements: the first caused the aircraft to smoke, the second struck the left wing causing a fire and a steep dive, and the third struck the cockpit area at low altitude, causing the airframe to disintegrate before impact. A Canadian Board of Inquiry later investigated the incident but faced significant hurdles, including the lack of flight recorders and evidence that Syrian authorities had erased approximately two and a half minutes of ATC communication tapes.

Final Conclusions

The Canadian Board of Inquiry, led by LCol J.A. Cann, concluded that the aircraft was destroyed by three surface-to-air missiles launched from a Syrian airfield. The board was unable to definitively determine if the attack was a result of a tragic identification error by Syrian air defense personnel or a deliberate act intended to pressure the United Nations regarding Israeli overflights of Syrian territory. The incident led to the establishment of August 9 as National Peacekeepers' Day in Canada.

UN Livery

The aircraft was painted in distinctive United Nations blue and white to identify it as a non-combatant peacekeeping asset.
