- The
United States employed a statistician to examine damaged planes returning
from bombing missions over Germany in World War II. He found that the number
of returned planes that had damage to the fuselage was far greater than
those that had damage to the engines. His recommendation was to
enhance the reinforcement of the engines rather than the fuselages.
If damage to the fuselage was far more common, explain why he made this
recommendation.
