In studying the theory of formation bombing, one soon faces questions of the best number of planes to use in the bombing group, how far apart it is best to fly them, and whether or not it is best to endeavor to have them spaced equidistantly. But unfortunately all textbooks seem strangely silent on these new problems.
The more complete theory for irregular targets which are variously presented can be built up later. But to simplify the treatment, let us here consider the target as having only one dimension, such as range, for example. Call T the target size, p the pattern size, S the average M.P.I. error, and P the probability of hits; T, p, and Y all being measured along the same axis.
We must study how T, p, S, and P are related. But in order to avoid dealing with quite so many variables, let us eliminate one of them by expressing the pattern size and the average M.P.I. error in terms of the size of the target. Then we need only determine P, the probability of hits, as a function of (p/T) and (S/T).
