MS Billy Mitchell (wearing a fur coat, probably racoon) speaking about the use of foreign air power (real audio). As conceded by every first calss power in the world, air power will determine the next war. Each nation is organized now, to mass air power at the beginning of a contest. Instead of the armies and navies being the objects of the attack of air power, they will go directly to the vital centers. Our future in this country depends on air power.
