moment she was stricken helpless; her motive power was

overwhelmed by the blind forces of Nature。  The wind caught her

as it would a soap…bubble and hurled her into the sea;

precipitating the most disastrous calamity in the annals of

aeronautics; since not only was the ship lost; but fifteen of her

crew of 22 officers and men were drowned。



The catastrophe created consternation in German aeronautical

circles。  A searching inquiry was held to explain the disaster;

but as usual it failed to yield much material information。  It is

a curious circumstance; but every successive Zeppelin disaster;

and their number is legion; has been attributable to a new cause。 

In this instance the accident was additionally disturbing;

inasmuch as the ship had been flying across country continuously

for about twelve months and had covered more miles than any

preceding craft of her type。  No scientific explanation for the

disaster was forthcoming; but the commander of the vessel; who

sank with his ship; had previously ventured his personal opinion

that the vessel was over…loaded to meet the calls of ambition;

was by no means seaworthy; and that sooner or later she would be

caught by a heavy broadside wind and rendered helpless; or that

she would make a headlong dive to destruction。  It is a

significant fact that he never had any faith in the airship; at

least for sea duty; though in response to official command he

carried out his duties faithfully and with a blind resignation to

Fate。



Meantime; owing to the success of the 〃L…I〃 in cross…country

operations; another and more powerful craft; the 〃L…II〃 had been

taken in hand; and this was constructed also for naval use。 

While shorter than her consort; being only 487 feet over all;

thisvessel had a greater beam55 feet。  This latter increase was

decided because it was conceded to be an easier matter to provide

for greater beam than enhanced length in the existing air…ship

harbours。  The 〃L…II〃 displaced 27 tonsfive tons in excess of

her predecessor。  In this vessel many innovations were

introduced; such as the provision of the passage…way connecting

the cars within the hull; instead of outside the latter as had

hitherto been the practice; while the three cars were placed more

closely together than formerly。  The motors were of an improved

type; giving an aggregate output of 900 horse…power; and were

divided into four separate units; housed in two engine…rooms; the

front car being a replica in every detail of the navigating

bridge of a warship。



This vessel was regarded as a distinct improvement upon the

〃L…I;〃 although the latter could boast some great achievements。 

But her glory was short…lived。  In the course of the Government

trials; while some 900 feet aloft; the huge vessel suddenly

exploded and was burned in the air; a mass of broken and twisted

metal…work falling to the ground。  Of the 28 officers and men;

including members of the Admiralty Board who were conducting the

official trials; all but one were killed outright; and the

solitary exception was so terribly burned as to survive the fall

for only a few hours。



The accident was remarkable and demonstrated very convincingly

that although Count Zeppelin apparently had made huge strides in

aerial navigation through the passage of years; yet in reality he

had made no progress at all。  He committed the identical error

that characterised the effort of Severo Pax ten years previously;

and the disaster was directly attributable to the self…same cause

as that which overwhelmed the Severo airship。  The gas; escaping 

from the balloons housed in the hull; collected in the confined

passage…way communicating with the cars; came into contact with a

naked light; possibly the exhaust from the motors; and instantly

detonated with terrific force; blowing the airship to fragments

and setting fire to all the inflammable materials。



In this airship Zeppelin committed an unpardonable blunder。  

He had ignored the factor of 〃internal safety;〃 and had

deliberately flown in the face of the official rule which had

been laid down in France after the Severo disaster; which

absolutely forbade the inclusion of such confined spaces as

Zeppelin had incorporated。  This catastrophe coming so closely as

it did upon the preceding disaster to the pride of the German

aerial fleet somewhat shook public confidence in these craft;

while aeronautical authorities of other countries described the

Zeppelin more vehemently than ever as a 〃mechanical monstrosity〃

and a 〃scientific curiosity。〃



The Zeppelin has come to be feared in a general manner; but this

result is due rather to stories sedulously circulated; and which

may be easily traced to Teutonic sources。  Very few data of a

reliable character have been allowed to filter through official

circles。  We have been told somewhat verbosely of what it can

accomplish and of its high degree of efficiency and speed。  But

can credence be placed in these statements?



When Zeppelin IV made its unexpected descent at Luneville; and

was promptly seized by the French authorities; the German War

office evinced distinct signs of uneasiness。  The reason was

speedily forth coming。  The captain of the craft which had been

captured forgot to destroy his log and other records of data

concerning the vessel which had been scientifically collected

during the journey。  All this information fell into the hands of

the French military department; and it proved a wondrous

revelation。  It enabled the French to value the Zeppelin at its

true worth; which was by no means comparable to the estimate

based on reports skilfully circulated for the benefit of the

world at large。



Recently the French military department permitted the results of

their expert official examination to be made public。  From close

investigation of the log…book and the diagrams which had been

prepared; it was found that the maximum speed attained by

Zeppelin IV during this momentous flight was only 45 miles per

hour!  It was ascertained; moreover; that the load was 10;560

pounds; and the ascensional effort 45;100 pounds。  The fuel

consumption had averaged 297 pounds per hour; while the fuel

tanks carried sufficient for a flight of about seven hours。  The

airship had attained a maximum height of about 6;230 feet; to

reach which 6;600 pounds of ballast had to be discarded。 

Moreover; it was proved that a Zeppelin; if travelling under

military conditions with full armament and ammunition aboard;

could carry sufficient fuel for only ten hours at the utmost;

during which; if the slightest head…wind prevailed; it could not

cover more than 340 miles on the one fuel charge。



This information has certainly proved a revelation and has

contributed to the indifference with which the Parisians regard a

Zeppelin raid。  At the outbreak of war the Zeppelin station

nearest to Paris was at Metz; but to make the raid from that

point the airship was forced to cover a round 500 miles。  It is

scarcely to be supposed that perfectly calm weather would prevail

during the whole period of the flight; so that a raid would be

attended by considerable risk。  That this handicap was recognised

in German military circles is borne out by the fact that a

temporary Zeppelin hangar was established at a point considerably

nearer the French capital; for the purpose of enabling a raid to

be carried out with a greater possibility of success。



The capture of Zeppelin IV revealed another important fact。  The

critical flying height of the airship is between 3;300 and 4;000

feet。  To attempt a raid at such an altitude would be to court

certain disaster; inasmuch as the vessel would have to run the

gauntlet of the whole of the French artillery; which it is

admitted has a maximum range exceeding the flying altitude of the

Zeppelin。  That the above calculation is within reason is

supported by the statements of Count Zeppelin himself; who h
