Bits and pieces of the BUK SA-11 missile involved in the downing of flight MH17

On 17 July 2014, Malaysia Airlines Flight MH17 was downed over eastern Ukraine, resulting in 298 fatalities. The crash occurred in an active conflict zone, raising significant concerns about the integrity and authenticity of physical evidence recovered from the site. This study presents a forensic investigation of foreign fragments collected from human remains, personal belongings and aircraft wreckage across three distinct recovery phases. Employing a suite of forensic techniques —including metallography, infrared spectroscopy (FTIR), Raman, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDX), and inductively coupled plasma mass spectrometry (ICPMS)— the fragments were characterized and compared against reference materials from dismantled BUK SA-11 missiles and missiles subjected to arena tests. The majority of fragments exhibited metallurgical and chemical signatures consistent with a BUK SA-11 missile, confirming its involvement in the incident. A small subset of non-missile fragments bearing explosive residues likely originated from nearby artillery or mortar activity. Despite the lack of site control and potential for evidence tampering, no signs of manipulation or substitution were identified, apart from one fragment recovered by a journalist. These findings demonstrate the robustness of forensic methodologies in preserving evidentiary integrity under compromised conditions and underscore the value of multidisciplinary approaches in complex international investigations.
