Abstract: The bombing of airliners has been a tactic used by terrorists during the past 40 years. Its prevention is a major priority by homeland security officials on a worldwide basis. In efforts to aid in the investigation of such bombings, this paper provides the results of the development of mathematical modeling and computer simulation for the study of aircraft bombings and associated forensics. As an assist in the forensic study, a number of photographs are provided to depict the normally observed physical characteristics of explosives damage upon aircraft and related materials. These are:

(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.

Our study illuminates and evaluates how these characteristics can be captured by computational mechanics. Finally, we use the laptop bombing of Daallo Airlines Flight 159 as a case study to demonstrate that event reconstruction can be accomplished for the purposof forensic investigations. Most of our supercomputer results are visualized by video animations in order to show the dynamic effects and phenomena of explosives and the associated event reconstruction.
