During the Battle of Britain the question "fighter or fighter-bomber?" had been decided once and for all: The fighter can only be used as a bomb carrier with lasting effect when sufficient air superiority has been won.
People today have forgotten they're really just a part of nature. Yet, they destroy the nature on which our lives depend. They always think they can make something better... They don't know it, but they're losing nature. They don't see that they're going to perish. The most important things for human beings are clean air and clean water.
I suppose we shall soon travel by air-vessels; make air instead of sea voyages; and at length find our way to the moon, in spite of the want of atmosphere.
The first rule of all air combat is to see the opponent first. Like the hunter who stalks his prey and maneuvers himself unnoticed into the most favourable position for the kill, the fighter in the opening of a dogfight must detect the opponent as early as possible in order to attain a superior position for the attack.
I can now state that I have succeeded in operating a motive device by means of [cosmic rays]. I will tell you in the most general way, the cosmic ray ionizes the air, setting free many charges - ions and electrons. These charges are captured in a condenser which is made to discharge through the circuit of the motor.
In the afternoon they came unto a land
In which it seemed always afternoon.
All round the coast the languid air did swoon,
Breathing like one that hath a weary dream.
Buddha says: "Do not flatter your benefactor!". Let one repeat this saying in a Christian church : it immediately purifies the air of everything Christian.
Alternate currents, especially of high frequencies, pass with astonishing freedom through even slightly rarefied gases. The upper strata of the air are rarefied. To reach a number of miles out into space requires the overcoming of difficulties of a merely mechanical nature.
