British Airships, Past, Present, and Future There are some principles, however, which, though they may not understand, they are nevertheless able to utilize; such, for instance, as the expansion of air by heat, and the creation of air currents. The Chinese Boy and Girl He had noticed something of this before, but whenever a strong wind was blowing he was accustomed to rise to a position above the air currents. The Master Key, an Electrical Fairy Tale Founded Upon the Mysteries of Electricity They understand air currents, know how to control the action and direction of their machines by shifting the position of their bodies, and by so doing avoid accidents which would be unavoidable by a novice. Flying Machines: construction and operation; a practical book which shows, in illustrations, working plans and text, how to build and navigate the modern airship There had been no sound; merely a change in the air currents of the room, but there was also the sense of another presence so clearly that Terry almost imagined he could hear the breathing.
