The prize-winning _Renard_ was quickly followed by the _España_, a
vessel of the same size and pattern, built for the Spanish government
by the same capable firm. During October this fine air ship made
several trial trips, carrying seven men. On November 2d she made
a splendid official test voyage of five hours, sailing from the
Astra aërodrome, at Beauval, to Paris and return, a distance of 250
kilometers in 5 hours and 10 minutes, or at the average rate of 31
miles an hour for the entire course. On November 5th, she started on a
ten-hour voyage, with five men and fuel for fifteen hours; but after
five hours, stopped her engine, and came to earth, owing to the bending
of the main shaft of the motor.
Besides the great auto balloons designed by Julliot and Surcouf, of
which the _République_ and _Colonel Renard_ are examples, a number of
convenient cruisers were brought forth in 1909 by the Zodiac Company.
One of the leading spirits in this enterprise was the famous Count de
la Vaulx, well known for his auto balloon designs and his long voyages
in sphericles. The chief merit of these modest air ships, which ranged
in volume from 25,000 cubic feet upwards, was cheapness and facility of
demounting and shipment. They were intended to popularize the art among
the masses, by giving everyone a chance to make a voyage at no great
expense. Besides their applicability to sport, touring, and public
uses, some were designed for considerable speed and endurance; which
qualities, together with their demountability and partial independence
of hangars, were expected to give them military value. They were of
the flexible type, so arranged that the various parts were easily
detachable, so as to be packed for transportation, by wagon or car.
The smaller ones might be called semi-navigables, since they had the
organs of a swift motor balloon, but, like the common sphericles,
could easily be demounted and hauled home—a likely issue on a day of
any considerable wind. The first one cost $5,000, cubed 25,000 feet
and, with its 16-horse-power engine, traveled 13 miles per hour. Its
hull had the form of a whale with docked and rounded tail. From this
body hung an elongated car with a screw at the rear and elevating
planes in front. Others of similar make, but larger, followed in rapid
order, their common mission being that advocated by Santos-Dumont, in
the early part of the decade, when he produced his _Runabout_ and
_Omnibus_—to give everybody a ride.
