IX. The Terror In The Air

“There's something queer about these aeroplane accidents at Belmore

Park,” mused Kennedy, one evening, as his eye caught a big headline in

the last edition of the Star, which I had brought uptown with me.

“Queer?” I echoed. “Unfortunate, terrible, but hardly queer. Why, it is

a common saying among the aeronauts that if they keep at it long enough

they will all lose their lives.”

“Yes, I know that,” rejoined Kennedy; “but, Walter, have you noticed

that all these accidents have happened to Norton's new gyroscope

machines?”

“Well, what of that” I replied. “Isn't it just barely possible that

Norton is on the wrong track in applying the gyroscope to an aeroplane?

I can't say I know much about either the gyroscope or the aeroplane, but

from what I hear the fellows at the office say it would seem to me that

the gyroscope is a pretty good thing to keep off an aeroplane, not to

put on it.”

“Why?” asked Kennedy blandly.

“Well, it seems to me, from what the experts say, that anything which

tends to keep your machine in one position is just what you don't want

in an aeroplane. What surprises them, they say, is that the thing seems

to work so well up to a certain point--that the accidents don't happen

sooner. Why, our man on the aviation field tells me that when that

poor fellow Browne was killed he had all but succeeded in bringing his

machine to a dead stop in the air. In other words, he would have won the

Brooks Prize for perfect motionlessness in one place. And then Herrick,

the day before, was going about seventy miles an hour when he collapsed.

They said it was heart failure. But to-night another expert says in

the Star--here, I'll read it: 'The real cause was carbonic-acid-gas

poisoning due to the pressure on the mouth from driving fast through the

air, and the consequent inability to expel the poisoned air which had

been breathed. Air once breathed is practically carbonic-acid-gas. When

one is passing rapidly through the air this carbonic-acid-gas is pushed

back into the lungs, and only a little can get away because of the rush

of air pressure into the mouth. So it is rebreathed, and the result is

gradual carbonic-acid-gas poisoning, which produces a kind of narcotic

sleep.'”

“Then it wasn't the gyroscope in that case?” said Kennedy with a rising

inflection.

“No,” I admitted reluctantly, “perhaps not.”

I could see that I had been rash in talking so long. Kennedy had only

been sounding me to see what the newspapers thought of it. His next

remark was characteristic.

“Norton has asked me to look into the thing,” he said quietly. “If his

invention is a failure, he is a ruined man. All his money is in it,

he is suing a man for infringing on his patent, and he is liable

for damages to the heirs, according to his agreement with Browne and

Herrick. I have known Norton some time; in fact, he worked out his ideas

at the university physical laboratory. I have flown in his machine, and

it is the most marvellous biplane I ever saw. Walter, I want you to get

a Belmore Park assignment from the Star and go out to the aviation meet

with me to-morrow. I'll take you on the field, around the machines--you

can get enough local colour to do a dozen Star specials later on. I may

add that devising a flying-machine capable of remaining stationary in

the air means a revolution that will relegate all other machines to the

scrap-heap. From a military point of view it is the one thing necessary

to make the aeroplane the superior in every respect to the dirigible.”

The regular contests did not begin until the afternoon, but Kennedy

and I decided to make a day of it, and early the next morning we were

speeding out to the park where the flights were being held.

We found Charles Norton, the inventor, anxiously at work with his

mechanicians in the big temporary shed that had been accorded him, and

was dignified with the name of hangar.

“I knew you would come, Professor,” he exclaimed, running forward to

meet us.

“Of course,” echoed Kennedy. “I'm too much interested in this invention

of yours not to help you, Norton. You know what I've always thought of

it--I've told you often that it is the most important advance since the

original discovery by the Wrights that the aeroplane could be balanced

by warping the planes.”

“I'm just fixing up my third machine,” said Norton. “If anything

happens to it, I shall lose the prize, at least as far as this meet is

concerned, for I don't believe I shall get my fourth and newest model

from the makers in time. Anyhow, if I did I couldn't pay for it--I am

ruined, if I don't win that twenty-five-thousand-dollar Brooks Prize.

And, besides, a couple of army men are coming to inspect my aeroplane

and report to the War Department on it. I'd have stood a good chance

of selling it, I think, if my flights here had been like the trials you

saw. But, Kennedy,” he added, and his face was drawn and tragic, “I'd

drop the whole thing if I didn't know I was right. Two men dead--think

of it. Why, even the newspapers are beginning to call me a cold,

heartless, scientific crank, to keep on. But I'll show them--this

afternoon I'm going to fly myself. I'm not afraid to go anywhere I send

my men. I'll die before I'll admit I'm beaten.”

It was easy to see why Kennedy was fascinated by a man of Norton's

type. Anyone would have been. It was not foolhardiness. It was dogged

determination, faith in himself and in his own ability to triumph over

every obstacle.

We now slowly entered the shed where two men were working over Norton's

biplane. One of the men was a Frenchman, Jaurette, who had worked with

Farman, a silent, dark-browed, weatherbeaten fellow with a sort of

sullen politeness. The other man was an American, Roy Sinclair, a tall,

lithe, wiry chap with a seamed and furrowed face and a loose-jointed

but very deft manner which marked him a born bird-man. Norton's third

aviator, Humphreys, who was not to fly that day, much to his relief, was

reading a paper in the back of the shed.

We were introduced to him, and be seemed to be a very companionable sort

of fellow, though not given to talking.

“Mr. Norton,” he said, after the introduction, “there's quite an account

of your injunction against Delanne in this paper. It doesn't seem to be

very friendly,” he added, indicating the article.

Norton read it and frowned. “Humph! I'll show them yet that my

application of the gyroscope is patentable. Delanne will put me into

'interference' in the patent office, as the lawyers call it, will he?

Well, I filed a 'caveat' over a year and a half ago. If I'm wrong, he's

wrong, and all gyroscope patents are wrong, and if I'm right, by George,

I'm first in the field. That's so, isn't it?” he appealed to Kennedy.

Kennedy shrugged his shoulders non-committally, as if he had never

heard of the patent office or the gyroscope in his life. The men were

listening, whether or not from loyalty I could not tell.

“Let us see your gyroplane, I mean aeroscope--whatever it is you call

it,” asked Kennedy.

Norton took the cue. “Now you newspaper men are the first that I've

allowed in here,” he said. “Can I trust your word of honour not to

publish a line except such as I O.K. after you write it?”

We promised.

As Norton directed, the mechanicians wheeled the aeroplane out on the

field in front of the shed. No one was about.

“Now this is the gyroscope,” began Norton, pointing out a thing encased

in an aluminum sheath, which weighed, all told, perhaps fourteen or

fifteen pounds. “You see, the gyroscope is really a flywheel mounted

on gimbals and can turn on any of its angles so that it can assume any

angle in space. When it's at rest like this you can turn it easily. But

when set revolving it tends to persist always in the plane in which it

was started rotating.”

I took hold of it, and it did turn readily in any direction. I could

feel the heavy little flywheel inside.

“There is a pretty high vacuum in that aluminum case,” went on Norton.

“There's very little friction on that account. The power to rotate the

flywheel is obtained from this little dynamo here, run by the gas-engine

which also turns the propellers of the aeroplane.”

“But suppose the engine stops, how about the gyroscope?” I asked

sceptically.

“It will go right on for several minutes. You know, the Brennan monorail

car will stand up some time after the power is shut off. And I carry a

small storage-battery that will run it for some time, too. That's all

been guarded against.”

Jaurette cranked the engine, a seven-cylindered affair, with the

cylinders sticking out like the spokes of a wheel without a rim. The

propellers turned so fast that I could not see the blades--turned

with that strong, steady, fierce droning buzz that can be heard a long

distance and which is a thrilling sound to hear. Norton reached over and

attached the little dynamo, at the same time setting the gyroscope at

its proper angle and starting it.

“This is the mechanical brain of my new flier,” he remarked, patting the

aluminum case lovingly. “You can look in through this little window in

the case and see the flywheel inside revolving--ten thousand revolutions

a minute. Press down on the gyroscope,” he shouted to me.

As I placed both hands on the case of the apparently frail little

instrument, he added, “You remember how easily you moved it just a

moment ago.”

I pressed down with all my might. Then I literally raised myself off

my feet, and my whole weight was on the gyroscope. That uncanny little

instrument seemed to resent--yes, that's the word, resent--my touch.

It was almost human in the resentment, too. Far from yielding to me, it

actually rose on the side I was pressing down!

The men who were watching me laughed at the puzzled look on my face.

I took my hands off, and the gyroscope leisurely and nonchalantly went

back to its original position.

“That's the property we use, applied to the rudder and the

ailerons--those flat planes between the large main planes. That gives

automatic stability to the machine,” continued Norton. “I'm not going

to explain how it is done--it is in the combination of the various parts

that I have discovered the basic principle, and I'm not going to talk

about it till the thing is settled by the courts. But it is there, and

the court will see it, and I'll prove that Delanne is a fraud--a fraud

when he says that my combination isn't patentable and isn't practicable

even at that. The truth is that his device as it stands isn't

practicable, and, besides, if he makes it so it infringes on mine. Would

you like to take a flight with me?”

I looked at Kennedy, and a vision of the wreckage of the two previous

accidents, as the Star photographer had snapped them, flashed across my

mind. But Kennedy was too quick for me.

“Yes,” he answered. “A short flight. No stunts.”

We took our seats by Norton, I, at least, with some misgiving. Gently

the machine rose into the air. The sensation was delightful. The fresh

air of the morning came with a stinging rush to my face. Below I could

see the earth sweeping past as if it were a moving-picture film. Above

the continuous roar of the engine and propeller Norton indicated

to Kennedy the automatic balancing of the gyroscope as it bent the

ailerons.

“Could you fly in this machine without the gyroscope at all?” yelled

Kennedy. The noise was deafening, conversation almost impossible. Though

sitting side by side he had to repeat his remark twice to Norton.

“Yes,” called back Norton. Reaching back of him, he pointed out the way

to detach the gyroscope and put a sort of brake on it that stopped its

revolutions almost instantly. “It's a ticklish job to change in the

air,” he shouted. “It can be done, but it's safer to land and do it.”

The flight was soon over, and we stood admiring the machine while Norton

expatiated on the compactness of his little dynamo.

“What have you done with the wrecks of the other machines?” inquired

Kennedy at length.

“They are stored in a shed down near the railroad station. They are just

a mass of junk, though there are some parts that I can use, so I'll ship

them back to the factory.”

“Might I have a look at them?”

“Surely. I'll give you the key. Sorry I can't go myself, but I want to

be sure everything is all right for my flight this afternoon.”

It was a long walk over to the shed near the station, and, together

with our examination of the wrecked machines, it took us the rest of the

morning. Craig carefully turned over the wreckage. It seemed a hopeless

quest to me, but I fancied that to him it merely presented new problems

for his deductive and scientific mind.

“These gyroscopes are out of business for good,” he remarked as he

glanced at the dented and battered aluminum cases. “But there doesn't

seem to be anything wrong with them except what would naturally happen

in such accidents.”

For my part I felt a sort of awe at the mass of wreckage in which Browne

and Herrick had been killed. It was to me more than a tangled mass of

wires and splinters. Two human lives had been snuffed out in it.

“The engines are a mass of scrap; see how the cylinders are bent and

twisted,” remarked Kennedy with great interest. “The gasoline-tank is

intact, but dented out of shape. No explosion there. And look at this

dynamo. Why, the wires in it are actually fused together. The insulation

has been completely burned off. I wonder what could have caused that?”

Kennedy continued to regard the tangled mass thoughtfully for some time,

then locked the door, and we strolled back to the grand stand on our

side of the field. Already the crowd had begun to collect. Across the

field we could see the various machines in front of their hangars with

the men working on them. The buzz of the engines was wafted across by

the light summer breeze as if a thousand cicadas had broken loose to

predict warm weather.

Two machines were already in flight, a little yellow Demoiselle,

scurrying around close to the earth like a frightened hen, and a

Bleriot, high overhead, making slow and graceful turns like a huge bird.

Kennedy and I stopped before the little wireless telegraph station of

the signal corps in front of the grand stand and watched the operator

working over his instruments.

“There it is again,” muttered the operator angrily.

“What's the matter?” asked Kennedy. “Amateurs interfering with you?”

The man nodded a reply, shaking his head with the telephone-like

receiver, viciously. He continued to adjust his apparatus.

“Confound it!” he exclaimed. “Yes, that fellow has been jamming me for

the past two days off and on, every time I get ready to send or receive

a message. Williams is going up with a Wright machine equipped with

wireless apparatus in a minute, and this fellow won't get out of the

way. By Jove, though, those are powerful impulses of his. Hear that

crackling? I've never been interfered with so in my experience. Touch

that screen door with your knife.”

Kennedy did so, and elicited large sparks with quite a tingle of a

shock.

“Yesterday and the day before it was so bad we had to give up attempting

to communicate with Williams,” continued the operator. “It was worse

than trying to work in a thunder-shower. That's the time we get our

troubles, when the air is overcharged with electricity, as it is now.”

“That's interesting,” remarked Kennedy.

“Interesting?” flashed back the operator, angrily noting the condition

in his “log book.”

“Maybe it is, but I call it darned mean. It's almost like trying to work

in a power station.”

“Indeed?” queried Kennedy. “I beg your pardon--I was only looking at it

from the purely scientific point of view. Who is it, do you suppose?”

“How do I know? Some amateur, I guess. No professional would butt in

this way.”

Kennedy took a leaf out of his note-book and wrote a short message which

he gave to a boy to deliver to Norton.

“Detach your gyroscope and dynamo,” it read. “Leave them in the hangar.

Fly without them this afternoon, and see what happens. No use to try for

the prize to-day. Kennedy.”

We sauntered out on the open part of the field, back of the fence and to

the side of the stands, and watched the fliers for a few moments. Three

were in the air now, and I could see Norton and his men getting ready.

The boy with the message was going rapidly across the field. Kennedy was

impatiently watching him. It was too far off to see just what they were

doing, but as Norton seemed to get down out of his seat in the aeroplane

when the boy arrived, and it was wheeled back into the shed, I gathered

that he was detaching the gyroscope and was going to make the flight

without it, as Kennedy had requested.

In a few minutes it was again wheeled out.

The crowd, which had been waiting especially to see Norton, applauded.

“Come, Walter,” exclaimed Kennedy, “let's go up there on the roof of the

stand where we can see better. There's a platform and railing, I see.”

His pass allowed him to go anywhere on the field, so in a few moments we

were up on the roof.

It was a fascinating vantage-point, and I was so deeply engrossed

between watching the crowd below, the bird-men in the air, and the

machines waiting across the field that I totally neglected to notice

what Kennedy was doing. When I did, I saw that he had deliberately

turned his back on the aviation field, and was anxiously, scanning the

country back of us.

“What are you looking for?” I asked. “Turn around. I think Norton is

just about to fly.”

“Watch him then,” answered Craig. “Tell me when he gets in the air.”

Just then Norton's aeroplane rose gently from the field. A wild shout

of applause came from the people below us, at the heroism of the man who

dared to fly this new and apparently fated machine. It was succeeded by

a breathless, deathly calm, as if after the first burst of enthusiasm

the crowd had suddenly realised the danger of the intrepid aviator.

Would Norton add a third to the fatalities of the meet?

Suddenly Kennedy jerked my arm. “Walter, look over there across the road

back of us--at the old weatherbeaten barn. I mean the one next to that

yellow house. What do you see?”

“Nothing, except that on the peak of the roof there is a pole that looks

like the short stub of a small wireless mast. I should say there was a

boy connected with that barn, a boy who has read a book on wireless for

beginners.”

“Maybe,” said Kennedy. “But is that all you see? Look up in the little

window of the gable, the one with the closed shutter.”

I looked carefully. “It seems to me that I saw a gleam of something

bright at the top of the shutter, Craig,” I ventured. “A spark or a

flash.”

“It must be a bright spark, for the sun is shining brightly,” mused

Craig.

“Oh, maybe it's the small boy with a looking-glass. I can remember when

I used to get behind such a window and shine a glass into the darkened

room of my neighbours across the street.”

I had really said that half in raillery, for I was at a loss to account

in any other way for the light, but I was surprised to see how eagerly

Craig accepted it.

“Perhaps you are right, in a way,” he assented. “I guess it isn't a

spark, after all. Yes, it must be the reflection of the sun on a piece

of glass--the angles are just about right for it. Anyhow it caught my

eye. Still, I believe that barn will bear watching.”

Whatever his suspicions, Craig kept them to himself, and descended.

At the same time Norton gently dropped back to earth in front of his

hangar, not ten feet from the spot where he started. The applause was

deafening, as the machine was again wheeled into the shed safely.

Kennedy and I pushed through the crowd to the wireless operator.

“How's she working?” inquired Craig.

“Rotten,” replied the operator sullenly. “It was worse than ever about

five minutes ago. It's much better now, almost normal again.”

Just then the messenger-boy, who had been hunting through the crowd for

us, handed Kennedy a note. It was merely a scrawl from Norton:

“Everything seems fine. Am going to try her next with the

gyroscope. NORTON.”

“Boy,” exclaimed Craig, “has Cdr. Norton a telephone?”

“No, sir, only that hangar at the end has a telephone.”

“Well, you run across that field as fast as your legs can carry you and

tell him if he values his life not to do it.”

“Not to do what, sir?”

“Don't stand there, youngster. Run! Tell him not to fly with that

gyroscope. There's a five-spot in it if you get over there before he

starts.”

Even as he spoke the Norton aeroplane was wheeled out again. In a minute

Norton had climbed up into his seat and was testing the levers.

Would the boy reach him in time? He was half across the field, waving

his arms like mad. But apparently Norton and his men were too engrossed

in their machine to pay attention.

“Good heavens!” exclaimed Craig. “He's going to try it. Run, boy, run!”

he cried, although the boy was now far out of hearing.

Across the field we could hear now the quick staccato chug-chug of the

engine. Slowly Norton's aeroplane, this time really equipped with

the gyroscope, rose from the field and circled over toward us. Craig

frantically signalled to him to come down, but of course Norton could

not have seen him in the crowd. As for the crowd, they looked askance at

Kennedy, as if he had taken leave of his senses.
