Excerpt from D'orcy's Airship Manual: An International Register of Airships With a Compendium of the Airship's Elementary Mechanics
Static aircraft derive their sustentation from a hull which is filled with a gas lighter than air; free balloons and airships consequently float in the atmosphere, like ships float on the sea, by virtue of buoyancy.
The airship's sustentation is, unlike that Of the aeroplane, independent Of forward motion, in other words, the airship can stay aloft without expending engine power, in which case it drifts with the pre vailing wind like a free balloon.
The airship is the outcome Of a century-long endeavor to endow the free balloon with inde pendent velocity whereby it would be able to navigate the atmosphere regardless Of winds in any direction desired; hence the now little used terms 0 navigable and dirigible balloon under which the airship first became known.
The very nature of the airship' S sustentation, which permits to assimilate the airship to the ship Of the sea, sufficiently justifies the retention of the term airship and the condemnation of the term dirigible,' the customary abbreviation Of dirigible balloon, which may reasonably be applied to the aeroplane too, Since it fails to specify the type of aircraft it is supposed to describe.
