The Improvised Explosive Device detonated by SA had a devastating effect. In Volume 3, I will describe its construction in greater detail. At this stage, it is sufficient to record that it comprised a high explosive element, triacetone triperoxide,which was surrounded by a large number of small metal items. Those metal items comprised 29.26kg of metal nuts and 1.47kg of screws or cross dowels. It is estimated that there were approximately 3,000 such items in total.
Those numbers give some idea of the terrible intent of SA and HA. They planned to cause as much harm to as many people as they could. In this Part, I deal with the effects of the explosion and the experience of some of the members of the public who were in the City Room and survived the Attack. This cannot be a complete summary of all of the effects of the Attack on each person who was in the City Room. It would be impossible to cover that in my Report. Rather, this Part sets out the accounts I heard from some of those most seriously affected by the events that night.
In Part 18, I will consider what happened to each of those who died following the detonation of the bomb. I will also consider whether any of those who were killed could have survived the Attack had the emergency response been different.
