The Way of the Air 6

The Way of the Air 6


Landing is the most difficult and delicate maneuver in flying; it
is a tricky performance to land an aeroplane, but it is doubly so
to land a seaplane. Should the surface of the sea be the least bit
choppy or rough, there is a grave risk of the floats breaking open,
and the machine turning turtle, or diving down through the sea and
precipitating the pilot to a watery grave.
 
 
WORK OF THE SEAPLANE
 
The work of the seaplane may be placed in two categories: first, work
from the shore, when a landing-station, bordering on the sea, is used
as a base; and, secondly, flying at sea, when the craft is taken out
on board a parent vessel, and flights are commenced from the middle
of the ocean. With regard to the former, the work is for the most
part of a defensive nature, as that of driving off invading enemy
craft, and patroling the coasts for enemy submarines. The work at sea
is principally scouting for fleets, for a seaplane observer, at an
altitude of 5000 feet, has a range of view ten times greater than the
look-out man of any battleship or cruiser.
 
In this latter case, flights are usually terminated and commenced from
the sea surface, alongside the parent ship; and when the craft are no
longer in use they are lifted on board by means of a large crane and
stowed away on a specially constructed deck.
 
From the point of view of interest, aeroplane work is preferable to
that of the seaplane. Nothing more boring and dreary can be imagined
than a long flight over an interminable stretch of blue water; the
aeroplane pilot does, at least, have an everchanging contour of hills
and valleys, rivers and woods, towns and villages beneath him, whereas
the seaplane man’s view is confined to sea, sky and horizon, with
perhaps an occasional passing ship.
 
One seaplane pilot of my acquaintance, in order to relieve the
monotony, always took his dog, a staid and wise-looking Scotch terrier,
with him. That dog can lay claim to holding the record among dogs of
the world, for he has now flown considerably over 2000 miles. His
method of aviation is peculiarly his own, for, once the machine has
started and got under way, he curls himself up in the body of the
fuselage and goes into a sound sleep, from which he does not wake until
the engine stops again.
 
Seaplane flying in these days is beset with dangers of many kinds.
 
As an example, I will attempt to portray the average day’s work of a
seaplane pilot on active service, somewhere in the North Sea.
 
A scene of unusual activity is revealed by the breaking dawn, lat. “X,”
long. “Y.” The sea is calm, the rising sun giving it that peculiar
grayish-green tint, over which the early morning mist hangs like a
pall. Through the mist can be seen the hazy, blurred outlines of the
Fleet: squat, lumpy monitors, slim and graceful cruisers, sharp-nosed
destroyers, submarines that hang, as it were, on to the surface of the
water. Great towering battleships, dignified and stately, look down
upon the smaller fry with apparent disdain. Far in the rear there is
what at first appears to be an ordinary smug-funneled tramp steamer;
but a glimpse of the huge crane and queer, elongated shapes along her
decks reveals the seaplane carrier.
 
Four o’clock in the morning. Though it is summer, the weather is cold
and raw, the chilly breeze bites knife-like through one’s clothes,
fingers are all thumbs--rather a disillusion of the joys of flying.
The engine stops, and coughs and splutters as if in protest at this
extraordinary behavior. Compass, maps, instruments are missing; the
petrol tanks are unfilled, or the oil has been forgotten.
 
At last, creaking and groaning, the crane is lowered, and fixed to the
craft. A few hoarse commands, and she is swung off the deck and dropped
gently on to the sea, and off she goes, bound on a reconnaissance trip
or target-registering. First taxi-ing far across the open sea, clear of
the Fleet. What a delightful sensation this is, skimming the water like
a seagull, dipping and bowing gracefully; but it is quite another story
when the sea is rough, and the swell threatens every moment to break up
the floats and submerge the craft. At last up into the air, 200, 300,
500, 1000 feet, circling round the now, seemingly, stationary Fleet;
how still and quiet they appear down below there!
 
The seaplane is usually a much slower craft to climb than the
aeroplane, and some time elapses before a decent altitude is reached.
The observer busies himself plotting out the course, testing the
wireless gear, and preparing his report.
 
Scouting is the object of the flight, and scouting implies, for the
most part, keeping a weather eye open for suspicious craft, enemy
battleships, cruisers, destroyers and enemy submarines, the latter
more easily distinguishable from a height, when the bed of the sea in
the more shallow portions can be read like an open book, sandbanks
standing out most prominently from the surrounding azure blue.
 
Target-registering, on the other hand, consists of following, or rather
attempting to follow, a damnably perverse raft, on which a large target
is lashed, at which the heavy guns of the Fleet are firing from a
distance of from fifteen to twenty miles, and the observer wirelessing
back the results of their attempts, also entering the same in his
report.
 
To the uninitiated this report would at first sight appear slightly
less understandable than a Chinese love letter or a Greek play. It
is divided into columns; first there is the time of the entry, next
the height at which the machine was flying, the approximate position,
and, last, the nature of the observation. For example: 11.55 a.m. 6000
feet. Lat. 90, long. 70:6. Large two-funneled steamers, apparently
merchantmen, observed proceeding in a south-westerly direction.
 
If the matter is of an urgent nature it is sent back to the Fleet
immediately by wireless, surely the most valuable asset to aviation
that exists, and without which aerial scouting and reconnaissance work
would be almost useless. The apparatus is light and extremely compact,
consisting of one or two Morse keys and an aerial. The range of
action--that is to say, the distance that a message can be either sent
or received--is not very great, but such as it is, is invaluable. In a
word, wireless in the Navy is as near perfection as it is possible for
a new science to be.
 
The observer makes a sudden movement with his hand in a south-westerly
direction. Far down on the distant horizon is the long black
sleuth-like form of an enemy destroyer. The wireless is soon busy
ticking the gladsome news to the Fleet, now far in the rear. More and
yet more black shapes appear, and then our own destroyers come up,
dashing through the sea, at well over thirty knots an hour, leaving
a line of churning white foam in their track. The enemy catch sight
of them and then turn north at full pelt, our own in hot pursuit,
until for fear of floating mines--it is a favorite trick of the Hun
sportsman, when pursued to drop mines behind him, in the hope that they
will strike the enemy ships--our own destroyers come back crestfallen
and downhearted.
 
_En passant_ it may be said that a seaplane battle is very similar
to a fight between two aeroplanes, though usually more slowly fought
out, and hence longer in duration. Such feats as “looping” or sudden
nose-dives are generally impossible.
 
The morning’s work is now completed, the recall signal is received via
the wireless, and the great bird turns for home, not, however, without
sighting several merchantmen and something which appears to be the
periscope of a German submarine, but which, however, proves on closer
inspection to be floating wreckage.
 
The British Fleet comes nearer into view, first the different shapes
and sizes of the varying craft, then the funnels, then the masts, the
rigging and the crew aboard. Throttling down his engine, the pilot
sinks gradually lower and lower, and lands on the smooth surface of
the water--strange to say a more difficult and more tricky feat than
to come down on the solid earth for reasons too numerous to mention in
this short chapter.
 
Another long “taxi” across the water to the side of the seaplane
carrier, the creaking crane comes sliding out again, is fixed to the
craft, which is hauled aboard, and stowed away until further required.
 
 
 
 
CHAPTER VII
 
A ZEPPELIN CHASE
 
 
“X or Y airships participated in the attack on Great Britain last
night; Z raiders were brought down.” Hard official words these, that,
read in the cold black and white of print, fail entirely to bring to
the reader’s mind a true sense of the danger and the nerve-racking
conditions under which this novel form of warfare is fought out.
 
Let us imagine, if we can, the difficulties the aeroplane pilot
has to face. It is dark--pitch dark--sky and earth are alike
indistinguishable. Flying at the best of times contains a more than
comfortable element of danger, and in the darkness this danger is
accentuated. The darkness deprives the air pilot of all sense of
direction and of locality, greatly hampers him in the maneuvering of
his craft, and renders unpleasantly possible a collision with another
aeroplane on similar errand bent.
 
Starting out, there are a hundred and one small details to be attended
to, as the testing of the engine, the trying of elevators and ailerons,
and the examination of the petrol and oil tanks, in order to ascertain
if there is a sufficiency of both to last a two or three hour trip.
All this to be performed in the dark, with the engine screeching
loud, so that a man may not hear a word, and the attendant mechanics
indistinguishable in the gloom.
 
Fortunately for the pilot, a small dry-cell electric lighting set is
installed in the body of every machine, and by this means the pilot is
able to distinguish his instruments--a most necessary adjunct to safe
flying--the altimeter, which records the height, “revmeter,” which
indicates the speed of the engine and the compass, more necessary than
any other instrument for night flying. Getting off from the ground is by no means a pleasant sensation. There
are hangars, high roofs, and chimney-stacks waiting to be collided
with, patches of thin and rarefied air, which will bump the machine
down as much as thirty feet at a time; the ever present danger of
engine failure, necessitating a descent to the darkened earth beneath,
