Thankfully, airplane crashes do not happen too frequently for any cause. Nevertheless, it is important to be able to understand what has happened in case of an airplane crash. In this talk, we examine two cases: (1) The laptop bombing case of Daallo Airlines Flight 159 in February 2016, near Mogadishu, Somalia; (2) The shot-down of Malaysia Airlines Flight 17 in Ukraine, 2015. We first examine five important characteristics of bombing: (i) The bet-out of metal onto itself; (ii) The jaggedness along the rim of the fracture; (iii) The feathering and sharpening along the rim of the debris; (iv) The pitting and milli-cratering of the surface; (v) The blackening of the damage surface. We develop computational mechanics for the modeling and supercomputing to evaluate how much it can capture the above five characteristics and, therefore, provide a forensics study for the Daallo Airlines Flight 159 and Malaysia Airlines Flight 17 airplane crash cases.
