What did Dahl not know when he aimed at the German bomber?

When Dahl aimed at the German bomber, one critical aspect was his uncertainty about whether he had successfully hit the plane. This lack of awareness is significant because, in the heat of combat, the immediate feedback of whether a target has been struck can be unclear. Dahl's focus was primarily on taking the shot, but the outcome of that shot—whether it actually impacted the plane or not—was unknown to him at the moment he fired.

The other options involve factors that were either clearer or already understood by Dahl at that time. For instance, he knew he was being attacked, he had positioned himself to engage the enemy aircraft, and he was aware of the operational status of the guns. Understanding these nuances enhances the overall narrative of Dahl's experience, emphasizing the chaos and uncertainty of battle.
