Three months after Malaysia Airlines Flight MH17 was violently brought down from the skies over Ukraine, there are still no definitive answers to what caused the tragedy. Civil conflict in the area prevented international experts from conducting a full and thorough investigation. The wreckage should have been collected and scrupulously re-assembled to identify all the damage, but this standard investigative procedure was never carried out. Until that’s done, evidence can only be gleaned from pictures of the debris, the flight recorders or black boxes and eye-witnesses’ testimonies. This may be enough to help build a picture of what really happened to the aircraft, whether a rocket fired from the ground or gunfire from a military jet.
