The Story of the Airship 4

The Story of the Airship 4



Those first ships were small, slow, lacked range, uncovered many
shortcomings. Flight training was done under adverse circumstances. Men
had to teach themselves to fly airships, then teach others to fly them.
 
The pilots were chiefly engineering students from the colleges, with a
sprinkling of Navy officers. They had to take their advanced training
abroad at British and French bases, because there were no facilities
here, and in fact did most of their flying abroad. By the end of the war
American pilots were manning three British airship bases and had taken
over practically all the French operations, including the large base at
Paimboeuf, across the Loire from St. Nazaire, on the French coast.
 
So the war was well along before American bases were set up and manned.
These were at Chatham, Mass., at Montauk and Rockaway, N. Y., at Cape
May, Norfolk and Key West. Like the airplane patrols the blimps saw
little action, though they had an advantage in that they could stay out
all day, while the short range planes of 1917-18 had to come back every
few hours to refuel.
 
A patrol airship at Chatham, Mass. missed its chance in that it was
adrift at sea with engine trouble when the German U-156 slipped into the
harbor at nearby Orleans and wiped out some fishing boatsthough it
might have done no better than the first plane which reached the scene,
whose few bombs did not explode.
 
The blimp patrols, however, uncovered one other type of activity. More
than once they spotted suspicious looking craft emerging under cover of
fog, from remote coves and inlets along the Long Island coast, fishing
boats and barges with improvised power plant and curious looking
paraphernalia on deck. Keeping the stranger in sight the blimp summoned
armored craft from shore which sent boarding crews on, found mines
destined for the New York steamship lanes.
 
A more important result of the blimp operations was the improvements in
design which were found, particularly in the “C” type ship, brought out
in 1918, of which 20 were built. They had much better performance in
range, power, could make 60 miles speed, were faster than any airships
except the Zeppelins. Navy officers and crews came to have high respect
for them.

Which led to one of the interesting aeronautic adventure stories of the
period. It happened just after the Armistice.
 
Men had come out of the war with imaginations afire over the
possibilities of aircraft. One challenge lay openthe Atlanticno one
had flown it.
 
In the breathing spell brought by the Armistice, the British were
preparing their new Zeppelin R-34 for the crossing; two English planes
were being shipped to Newfoundland to try to fly back; the U. S. Navy
had a seaplane crossing in prospect. There was even a German plan. A new
Zeppelin had just been finished at Friedrichshafen when the Armistice
was signed, and the crew planned to fly it to America as a
demonstrationbut authorities got wind of it and blocked the venture.
 
But of all the Atlantic crossings about which men were dreaming in early
1919, none is more interesting than the one projected for the little
blimps.
 
The C-5, newest of the non-rigid airships built for the Navy, was
stationed at Montauk, and there one night a group of officers sat
intensively studying charts and weather maps. St. John’s, Newfoundland,
1,400 miles away, would be the first leg of the trip. It was easily
within the cruising radius of the ship, particularly if they got helping
winds, which they should if the time was carefully picked. From there to
Ireland was another 1850 miles, also within range with the prevailing
westerly winds.
 
Permission was asked from Washington, and the Navy flashed back its
approval and its blessing, assigned five experienced officers to the
project: Lieut. Comdr. Coil, Lieuts. Lawrence, Little, Preston, and
Peck. The USS Chicago was sent ahead to St. John’s to stand by and give
any help needed.
 
Shortly after sunrise on May 15, 1919, motors were warmed up and the
ship shoved off from the tip of Long Island with six men aboard headed
for Newfoundland. At 7 o’clock the next morning they circled over the
deck of the _Chicago_, dropped their handling lines to the waiting
ground crew on a rocky point at St. John’s. The first leg had been made
in a little more than 24 hours, at an average speed of nearly 60 miles
per hour.
 
The morning was clear and comparatively calm. Coil and Lawrence went
aboard the _Chicago_ to catch a little sleep before the final hop over
the ocean. The others saw to re-fueling the C-5, stowing provisions
aboard, topping off a bit of hydrogen from the cylinders alongside.
Mechanics swarmed over the motors. All was well.
 
But about 10 o’clock gusts began to sweep down from Hudson’s Bay,
dragging the ground crew over the rocks. There were no mooring masts in
those days. A modern mast would have saved the ship. More sailors were
put on the lines and word sent to Coil and Lawrence. If the ground crew
could hold the ship till the pilots could get aboard and cut loose, the
storm would give them a flying start over the Atlantic.
 
But the wind blew steadily stronger as the commander was hurrying
ashore. It reached gale force, hurricane force, 40 knots, 60 knots in
gusts, varying in direction crazily around a 60-degree arc. It picked
the ship up and slammed it down, damaging the fuselage, breaking a
propeller. Little and Peck climbed aboard to pull the rip panel and let
the gas out. After the storm passed, they could cement the panel back
in, reinflate the bag and go on.
 
But the fates were against them. The cord leading to the rip panel
broke. Desperately, the two men started climbing up the suspension
cables to the gas bag with knives, planning to rip the panel out by
hand. But a tremendous gust caught the ship, lifted it up. Seeing the
danger to the crew, Peck shouted to them to let go, and he and Little
dropped over the side. Little broke an ankle.
 
The ship surged upward, crewless, set off like another “Flying Dutchman”
across the Atlantic, was never seen again.
 
Just three days later Hawker and Grieve set out from St. John’s, landed
in the ocean. Alcock and Brown cut loose their landing gear a month
later and landed in Ireland. One of the three Navy seaplanes, the NC-4,
reached Europe on May 31 and the British dirigible R-34 set out on July
2 for its successful round trip to Mitchel Field.
 
But for a trick of fate and the lack of equipment available today, a
blimp would have been first to get across.
 
Many things happened in the airship field between the two wars, but most
of them affected non-rigid airships only indirectly, as the Navy was
primarily concerned with the larger rigids.
 
The loss of the Hindenburg by hydrogen fire (which American helium would
have prevented), coming on the heels of tragic setbacks in this country
was enough to dismay anyone except Commander C. E. Rosendahl and his
stouthearted associates at Lakehurst Naval Air Station.
 
They didn’t give up. Setbacks were inevitable to progress. Count
Zeppelin had built and lost five rigid airships prior to 1909, but he
went on to build ships which were flown successfully in war and peace.
If the Germans, using hydrogen, could do this, Americans, with helium,
should not find it impossible, Lakehurst reasoned. And if they had no
rigid airships to fly and no immediate likelihood of getting any they
would use blimps.
 
The Navy was more familiar than the public with what the British and
French airships had accomplished in the first war. Studying, as all Navy
officers were doing in that period, the various possibilities of attack
and defense, in case the war then threatening Europe should sweep across
the Atlantic, they came to the conclusion that the coast line of America
was no more remote from German submarines in 1938 than the coast of
England was in 1914.
 
The airplane had improved vastly in speed, range, and striking power,
and their very multiplicity had ruled out the blimps over the English
channel, even if helium was available, but those conclusions did not
hold along the American coast.
 
The heroic part played by Allied blimps was a part of the legend of the
airship service. Nothing new developed in war had subtracted anything
from the ability of American airships to do in this war what British
non-rigids had done in the last. Commander J. L. Kenworthy and after him
Commander G. H. Mills as commanding officer at Lakehurst turned to
non-rigids.
 
Under Mills was instituted, quietly, unostentatiously, with what ships
he had, a series of practice patrols to determine the usefulness of
airships in this field, to discover and perfect technique, and to train
officers and men.
 
Lakehurst had a curious conglomeration of airships to start with. There
were two J ships of immediate post-war type, with open cockpits, 210,000
cubic feet capacity; two TC ships, inherited from the Army, of more
modern design, and larger size; the ZMC2, an experimental job built to
study the use of a metal cover, and about to be scrapped after nine
years of existence; the L-1, the same size as the Goodyear ships,
123,000 cubic feet, the first modern training ship, which would be
joined later by the L-2 and L-3; the G-1, a larger trainer of Goodyear
Defender size, useful for group instruction, and the 320,000 cubic foot
K-1, which had been built for experiments in the use of fuel gas. Only
the K-2, prototype of the 416,000 cubic foot patrol ships later ordered
could be called a modern airship, though the Army dirigibles also had
good cruising radius.
 
Yet with this curious assortment of airships of various sizes, types and
ages, the Navy carried on practice patrols covering the areas between
Montauk and the Virginia Capes, flying day after day, built an
impressive accumulation of flight data, missed very few days on account
of weather, made it a point not to miss a rendezvous with the surface
fleet. More than any one thing it was this demonstration, over an
18-month period, which led to the revival of an airship program in this
country, the ordering of ships and land bases.
 
Let us see what a blimp patrol is like. The airship can fly up to 65
knots or better, but this is no speed flight. The motors are throttled
down to 40 knots, so that the crew may see clearly, take its time, study
the moving surface underneath, scrutinize every trace of oil smear on
the surface, alert for the tell-tale “feather” of the submarine’s wake,
air bubbles, a phosphorescent glow at night, for even a bit of debris
which might conceal a periscope.
 
A school of whales, a lone hammerhead shark on the surface or submerged
stirs the interest of the patrol, offers a tempting live target for the
bombs,light charges with little more powder than a shot gun shell uses.
Now a ship records a direct hit on a shark’s back 500 feet below. He
shakes his head, dives to escape this unseen enemy aloft. The airship
gives chase, follows the moving shadow below, so strikingly resembling a submarine, finds the practice useful.
