Creating air bases and then later vacating them after intensive use has caused harm, as has the failure in airpower’s first seventy years to create aircraft than can be repurposed or deconstructed with minimal environmental harm. The book argues that, during both peace and war, air forces have far greater carbon footprints than armies and navies.
Airpower can be considered a function of air supremacy and numbers. Roughly speaking, a combatant side that has 100% or near 100% control of the skies has air supremacy; an advantage of some 70–90% would indicate air superiority. A 50/50 split is air parity; lower than this, one side may be said to be air denied or air incapable.
Air power is a function of the degree of air superiority and numbers or types of aircraft, but it represents a situation that defies black-and-white characterization. The degree of a force's air control is a zero-sum game with its opponent's; increasing control by one corresponds to decreasing control by the other.
Having said that, though, it is important to keep logic at the forefront in cases like this. And though the terrible accident in Washington D.C. is rattling, it's only going to make flying that ...
Life exists all over the Earth in air, water, and soil, with many ecosystems forming the biosphere. Some of these are harsh environments occupied only by extremophiles . Life has been studied since ancient times, with theories such as Empedocles 's materialism asserting that it was composed of four eternal elements , and Aristotle 's ...

Aerodynamics (Ancient Greek: ἀήρ aero (air) + Ancient Greek: δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. [1] It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics.
The original air-breathing gas turbine jet engine was the turbojet. [3] It was a concept brought to life by two engineers, Frank Whittle in England UK and Hans von Ohain in Germany. The turbojet compresses and heats air and then exhausts it as a high speed, high temperature jet to create thrust.
