We were asked to select and combine materials to make a functional model air-raid shelter. It had to meet two main criteria: to contain a space inside for sheltering in; and to be strong and stable to withstand attack from above. (Elegance and beauty in design was not essential!)
In order to establish whether our model shelters met the design brief, a replica bomb of appropriate size and weight (a brick) was dropped on them. In most cases, there was little visible damage caused to the structures, however in some, there was an initial flattening of the roof from the impact which is likely to have resulted in injury to those seeking safety within.
