The purpose of the paper is to present a collection of thoughts which have evolved in a Structural Engineer's mind over a period of time through visiting and observing the results of many terrorist bombings. The considerations, all aimed at alleviating human suffering, fall into three categories. (1) Predicting the outcome from a possible threat scenario. (2) Recommending procedures for personnel before an expected event. (3) Recommending details in building design to reduce hazards. This paper is based on experiences of the United Kingdom's too many bombing incidents, and outlines in general terms its glazing studies.
