On Feb. 10, 2012, at 10:45LT a Bosnia and Herzegovina Armed Forces helicopter Mil Mi-8TV-1, crashed near the village of Bukovica Kalinovik, 40 kilometers south of Sarajevo, during a humanitarian mission to deliver food, medicines and fuel.
Someone was filming from inside as the helicopter approached the ground (for landing?). Suddenly something happens (01:57 of the footage below) and the chopper starts rotating out of control.
Bad weather was reported as a possible root cause of the crash even if the video doesn’t seem to show poor visibility, rain or particularly strong winds.
Fortunately all 11 people who were on board escaped the helicopter uninjured.
