INTRODUCTION
Lighter-than-air craft consist of three distinct types:
Airships, which are by far the most important, Free Balloons, and
Kite Balloons, which are attached to the ground or to a ship by a
cable. They derive their appellation from the fact that when
charged with hydrogen, or some other form of gas, they are
lighter than the air which they displace. Of these three types
the free balloon is by far the oldest and the simplest, but it is
entirely at the mercy of the wind and other elements, and cannot
be controlled for direction, but must drift whithersoever the
wind or air currents take it. On the other hand, the airship,
being provided with engines to propel it through the air, and
with rudders and elevators to control it for direction and
height, can be steered in whatever direction is desired, and
voyages can be made from one place to another--always provided
that the force of the wind is not sufficiently strong to overcome
the power of the engines.
