The prisoners' attitudes about the air raid are very flippant- they don't really notice, nor do they care. The guards and took refuge in the bomb shelters and left the prisoners on the blocks, not so safely secured, but that was not the prisoner's primary concern. Death was so tangible to all the prisoners at this point that air raid warnings and aerial bomb attacks were welcome interruptions. The prisoners didn't mind dying if it meant that their enemies were going to be hit as well, not to mention that death would end the torturous suffering they had to endure. When it is said that the factory in which Elie's own father is working is being bombed at that moment he remarks,
"we no longer feared death, in any event this particular death. Every bomb that hit filled is with joy, gave us renewed confidence."
When the air raid bomb went off in Chapter 4 the prisoners' concern was not with safety but with two steaming cauldrons of soup that had been left out. Hunger was a more primary instinctual concern than surviving a possible aerial bomb attack, especially since it could mean that the end of the war and suffering of the Jews was close to coming to an end.
