Investigation Summary
The ECMM helicopters were operating in a corridor and at an altitude previously coordinated with Yugoslav authorities. The formation consisted of two Italian-operated AB-206L helicopters. At approximately 14:00 local time, two Yugoslav MiG-21bis fighters scrambled from Željava Air Base. Pilot Emir Šišić, flying the lead MiG, was ordered to engage the targets. He fired two R-60 air-to-air missiles; the first missed, but the second struck the lead helicopter (MM80557), causing it to explode and crash near the village of Podrute. The second helicopter managed to evade the attack by performing a violent emergency landing. The Yugoslav military initially claimed the helicopters were flying illegally or were escorting Croatian forces, but radar data and eyewitness accounts confirmed only two white ECMM aircraft were present. The attack occurred just one day before a scheduled UN-brokered ceasefire was to take full effect.
Final Conclusions
The downing was a deliberate act of military aggression against unarmed diplomatic observers. Legal proceedings in Italy and Croatia resulted in the conviction of pilot Emir Sisic and his superiors. Sisic was sentenced to 15 years in prison by an Italian court. General Ljubomir Bajic and Colonel Dobrivoje Opacic were initially sentenced to 20 years in prison by a Croatian court; in 2013, an Italian Appeals Court sentenced them in absentia to 28 years. Colonel Bozidar Martinovic was acquitted by the same Italian court. The Yugoslav Ministry of Defence admitted the error by suspending the Air Force commander and accepting the resignation of General Veljko Kadijevic.
