Carl Andrew Spaatz quotes:

In our victory over Japan, airpower was unquestionably decisive. That the planned invasion of the Japanese Home islands was unnecessary is clear evidence that airpower has evolved into a force in war co-equal with land and sea power, decisive in its own right and worthy of the faith of its prophets.

Air control can be established by superiority in numbers, by better employment, by better equipment, or by a combination of these factors.

The first and absolute requirement of strategic air power in this war was control of the air in order to carry out sustained operations without prohibitive losses.

If we succeeded, we will have the primary satisfaction of ending the war
