How many bombing missions were flown in World War I?

The selection of 57 bombing missions flown in World War I is grounded in historical records which indicate that the use of strategic bombing was in its infancy during this conflict. While bombing missions were conducted, the scale and frequency were significantly lower than in subsequent conflicts, particularly World War II. The limited technological capabilities of the time, including aircraft range, bombing accuracy, and overall strategy, restricted the ability to conduct numerous bombing operations.

In World War I, the emphasis was largely on ground-based warfare and aerial reconnaissance rather than widespread aerial bombing campaigns. The figure of 57 reflects the early experimentation with bombing techniques and the initial integration of aircraft into military strategy, illustrating the significant advancements and changes that would occur in military aviation in the years to follow. This historical context helps validate the accuracy of the chosen answer.
