The Story of the Airship 10

The Story of the Airship 10


No blimps have done this. The fleet might see no need for them to go out
for long periods. However, the possibility has been established, and
might be useful in the emergencies of war, or accident. While the
primary usefulness of the blimp lies in the coastal waters, it can go to
sea if neededand stay outcan be used in convoy work or as a listening
post.
 
Other improvements were uncovered during the experiments. A sea anchor
or drogue was devised to enable the airship to “lay to” for extended
periods, without consuming fuel, in case it wishes to use its listening
devices against submarines, make repairs or for other purposes. Plans
have been worked out for landing on the water in quiet bays in calm
weather, utilizing flotation gear, or a three-point mooring to ordinary
mud anchorsfacilitating servicing from nearby Coast Guard stations.
 
Perhaps a significant thing about these experiments is that the
principles seem applicable as well to rigid airships. The ability to
pick up ballast in flight may well eliminate the necessity for
ballast-recovery devices, with a substantial saving in cost, and an
impressive saving in weight.
 
By eliminating the heavy condensers, and translating that weight-saving
into fuel, it is estimated that the range of a ship of the Los Angeles
size could be increased by 20 percent and ships of the Akron-Macon size
by 15 percent, in the last case amounting to 1,250 miles of additional
cruising radius.
 
A trans-oceanic passenger airship could start out with virtually no
water ballast at all except a minimum amount for maneuvering, use its
fuel supply as ballast and pick up sea water as needed. This could be
done at 500 feet elevation, at the rate of 80 gallons a minute, using a
30 horsepower motor, could be done in half an hour a day. The ship need
not slow down materially while doing this.
 
Application of this principle to military airships of the rigid type
might be still more significant. The chief use for the rigid airship in
war would seem to be as a high speed airplane carrier, whose planes
would increase many fold its own reconnaissance range, and would be
expected also to do the major part of what fighting became necessary in
case of enemy contact. The airship itself in that situation would put
more dependence on its speed of retreat and its ability to seek cover in
clouds as the submarine does beneath the surface, than on its own
machine guns and cannons.
 
One thing brought urgently home to us in the first weeks of the present
war is that oceans are wide, and that the movements of even a huge enemy
fleet are difficult to discover in those endless expanses of water.
 
Large military airships of five or ten million cubic feet helium
capacity might prove exceedingly useful, if they were able to operate
away from their base for weeks or even months at a time, and they might
be able to do this by utilizing devices similar to those developed for
smaller non-rigids, resting on the sea in calm waters, mooring to
anchored masts they could lower into the water, picking up fuel from
tankers, getting supplies from neighboring shipsin addition to what was
carried to them from the fleet by their own planes.
 
 
 
 
CHAPTER VII
Adventures of the Goodyear Fleet
 
 
[Illustration: Airships flying in formation]
 
One of the lesser romances at least of aeronautics is the story of the
Goodyear airship fleet.
 
There is thrill and adventure in the narrative, daring and
resourcefulness, hazards faced by men who believed in their
craftchances which were usually won. So this chapter might well be
dedicated to Airship Captain Charles Brannigan and Balloon Pilot Walter
Morton.
 
Morton was an old timer, who had flown balloons with Tom Baldwin, in the
far corners of the country. Between times he worked in the Goodyear
balloon room, a practical mechanic who could always make things work,
the salt-of-the-earth workman whom every foreman swore by, the aide
every pilot wanted alongside. Steady, self-effacing, courageous, with an
instinct for the right thing to do in emergency, Morton feared but one
thing. That was lightning.
 
He had flown many times through lightning storms prior to the helium
era, beneath a bag filled with inflammable gas, but he didn’t like it.
He knew its swift striking power.
 
“I could almost see the Old Fellow standing there throwing those darts
at us,” said Morton one afternoon in 1928, as he scanned the skies
before taking off in a balloon race out of Pittsburgh. “One would flash
past and miss, and he would say ‘I’ll get you next time,’ and there
would come another. And you can’t dodge in a balloon.”
 
The Old Fellow scored a direct hit that afternoon. Morton was flying
with Van Orman, Gordon Bennett Cup winner. The uncertain weather of the
afternoon had resolved itself less than an hour after the take-off, and
eight balloons were being tossed as a juggler tosses weights, a thousand
feet high, 10,000 feet, caught and tossed aloft again just before they
touched the ground. Morton’s balloon was hit at 12,000 feet, caught
fire, alternatively fell like a plumb bob or parachuted in the net,
landed without too much of a shock. Van Orman, unconscious, sustained a
broken ankle. Morton had been instantly killed.
 
But aerologists learned things that afternoon about the force of
vertical movements of the air. The balloons gave a perfect track of what
went on. One balloon was falling so fast that sacks of ballast thrown
overboard lagged behind it, while a hundred yards away another balloon
was shooting upward at similar speed.
 
We still know less than we should about the movements of the air, this
new world into which the Aeronautic Age is moving. The Pittsburgh
tragedy may save many lives, avoid other tragedies.
 
The Brannigan story is shorter, no less dramatic. High-spirited, keen, a
captain whose ship and crew must always be shipshape, Brannigan had come
to Goodyear from the Armywhere he had already distinguished himself by
making repairs in mid air to the semi-rigid Roma, ripped by a splintered
propellersaving a comrade as an incident to the jobhad quickly won his
captaincy at Goodyear, was one of its best flyers.
 
At Kansas City one afternoon in 1931 a Kansas twister headed for the
airport. Seeing the weather uncertain Brannigan had stopped passenger
flying, put his ship on the mast. Now he ordered his mechanic to get off
and cut the ship loose. Once aloft, with helium gas, he was not afraid
of any storm that blew. But before the ship could clear the mast, the
storm had struck, with full fury. The anchors holding the mast pulled
out of the ground and the ship, with the mast attached, was hurled into
the nearest hangar, ripping one motor off. That was Brannigan’s cue to
jump. The door had been propped open for a photographer’s camera. But he
had one motor left, the bag was undamaged, the mast had fallen clear. He
wouldn’t give up his ship as long as there was a chance to save it.

However the storm was not to be denied, and before he could get
altitude, the wind threw the ship into a nest of high-tension wires, set
it afire. Brannigan climbed out, walked to a nearby automobile,
transferred to a second car enroute to the hospital after a
collisionand died the next day from third-degree burns.
 
He called Furculow, his co-pilot, just before the end, told him to see
that the men in the crew were taken care of, that they were not
penalized for the loss of the ship. Furculow, now flying airships for
the Navy, is not the only man in Goodyear who will not forget Charley
Brannigan. It is on such men that the traditions of the service are
built. Any cause for which men give their lives cannot be held lightly.
 
The Goodyear Company had built a few airships of its own prior to the
1925 Pilgrim, when helium became available. Best known of these was the
“Pony Blimp” which operated out of Los Angeles from 1919 to 1923, flew
passengers to Catalina, worked for the movies in Arizona and Wyoming.
 
But the real beginning came with the Pilgrim, the larger Puritan and
still larger Defender, as the Goodyear fleet came into existence in
1928-29.
 
Early pilots had no specific instructions except to take the ships out
and fly themfly them hard, find out all they could about them, see what
weaknesses and shortcomings there were and how to improve them. It was
another test fleet, repeating the history of the automobile.
 
The pilots were supposed not to get hurt, but they were to fly in all
kinds of weather they felt it safe to fly in. They might lose a few
ships, but were expected to be able to walk away from them, not to get
in any trouble they couldn’t get out of. They had an advantage over Army
and Navy fliers in having a free hand as to where they might go. They
were expected to make mistakes but should learn from them.
 
Such instructions, largely unwritten, acted as a challenge to the
pilots, a high-spirited and courageous group. Starting with a few men
who had flown airships in the World War, or helped build them in the
balloon room and the machine shop, they added some technical school
graduates in 1929, and others as needed.
