CHAPTER XV

THE MOONLIGHT FLIGHT

The time for talking had passed. With the motor working noisily, and the

twin propellers churning the air, they could hardly have heard the

discharge of one of the 'Big Berthas', as the Allies were wont to call

the monster Krupp guns, and so called them because a woman whose maiden

name had been Bertha Krupp, owned a big interest in the works where they

were manufactured.

All was dark around and below them. Above the stars shone, and gave a

small amount of cold, cheery light. Tom had made a study of the heavens,

and was able to steer by means of the stars. The aviator is often as

much dependent on compass and heavenly bodies to shape his course as the

sailor hundreds of miles away from land.

Tom was in no especial hurry. He had carefully thought out his plans,

and meant to pass over Verdun at just a certain time. Then would come

the two lines of hostile trenches, and the ordeal of searchlights and

shrapnel. Once that was done with, they had really little further to

fear.

The minutes slipped away. Under ordinary conditions they were accustomed

to making that thirty miles in just about half that number of minutes,

thanks to the ability of the speedy Nieuports to cover distance. It

would be twice that now before they would find themselves at the front.

Already they could see various signs to tell them they were drawing

near. Rockets used as signals of various kinds ascended at intervals,

and burst. Others of the star variety, and which discharged glowing

white electric balls that lighted the earth below, could also be seen.

One side or the other apparently had some reason for desiring to

scrutinize a special sector of terrain in No-Man's-Land, the disputed

region lying between the hostile trenches.

Jack used his eyes to advantage. These things had not yet grown stale

with him, for he still found himself filled with awe and wonder when

gazing down from a lofty height at the world shrouded in darkness below.

There within a comparatively short distance, that might not be over

twenty miles, a round million of soldiers were gathered, armed with

numberless engines of destruction of the most ponderous nature

imaginable. It was enough to give any one a genuine thrill, and Jack

felt such a sensation creeping over him.

The crucial time had now come. They were passing over the line of the

French trenches. Jack knew this from various signs, and also that in

another minute they might expect to be spotted by some of the enemy

searchlights. These would be unmasked, and trained on the heavens in the

effort to locate the cause of that well known clattering noise above.

This speedily came about. First one long shaft of dazzling light rushed

back and forth; then others joined in the hunt, until presently they

focussed on the progressing two-seater pushing north.

Then began the bombardment. Numerous anti-aircraft guns were poking

their noses upward in anticipation of just such a call. Their crews

commenced to shower the shrapnel around and below the bird of passage,

whose mission, whatever it might prove to be, could mean only evil to

the Teuton cause.

All this racket was lost upon the two so far above the earth. They heard

nothing of the bleat of the firing guns. Even the bursting of shrapnel

went unheeded, save at a time when a shell exploded close by, and was

faintly heard.

Tom was wisely taking but little chance. He maintained an altitude that

prevented most of the shrapnel from coming anywhere near the plane.

They crossed the enemy front, and sped on. The bombardment diminished in

fury as they left the first and second line trenches behind them. It was

continued to some extent from an elevation further back, but as Tom knew

of this formation, and had crept up still higher, no accident happened

to them.

At last the air service boys were fully launched on their night voyage

through the upper currents. Tom waited until he considered that it was

really safe to change their course. He did not want to betray his

movements in case some daring Boche pilot started up in a swift Fokker

machine to pursue them.

Once he shut off the engines and volplaned down a thousand feet or more.

This was done because it was intensely cold up where they were; and the

reasons that had kept them at such a high altitude existed no longer.

Then again Tom wished to listen to discover if there was another

aircraft near them; and this could be done only when his motor was

silent.

"No pursuit, Jack!" he managed to call to his chum before they once more

straightened out, and again allowed the motor to send forth its loud

hum.

Jack had no chance to make any sort of reply. It did not matter, for he,

too, had eagerly listened, and had failed to catch any telltale sound.

Immediately Tom shaped a new course. No longer were they heading toward

the north by east, but directly east. There some forty miles, more or

less, away, lay the city of Metz, the object of their mission.

After moving along in this fashion for a short time Tom drove his

machine more slowly. He was watching for the rising of the old moon

ahead, where the horizon was already lighted with her near approach.

How strange she looked peering above the edge of the world as though

curious to see all that was going on in this troubled hemisphere. Jack

thought he had never witnessed a more peculiar spectacle. But at least

this fragment of a moon would be likely to afford them the necessary

illumination required when they attempted to land in a field that

neither of them had ever seen before, and only knew through information

imparted by means of their chart, and its accompanying notes.

Some other pilot had doubtless been over this same route on previous

occasions; yes, and even landed in that identical field. He had made the

chart; and the accompanying memoranda consisted of his personal

experiences.

Already the moon had dispelled some of the cheerless gloom round about

them. It was still cold up in that upper strata of rarefied air; but

their fur-lined garments kept them from suffering. Besides this, they

were young and vigorous, and their blood was warm, and they were excited

with their mission and able to ignore any physical discomfort that might

come to them.

Jack continued to stare ahead as time passed. He was looking for some

sign of the city towards which they were flying. Tom, on his part, often

took note of his compass, then flashed a glance up at the stars, and

finally sought to discover some landmark far down below that was marked

upon the chart.

He had the utmost confidence in his own judgment, and believed he would

bring up at the identical place which was their goal.

Tom now volplaned again, wishing to draw nearer to the earth. It was

while thus dropping, with engine muffled, that his ears caught a sound

calculated to give him an uneasy feeling.

This was undoubtedly the whirr of a propeller beating the air in furious

fashion. It also came from behind. Jack, too, had caught the sound, and

was thrilled with sudden apprehension of impending trouble.

They were undoubtedly being pursued, and by a much faster plane than

their own. This would mean that presently they would be overtaken and

fired upon. It was not in the nature of Tom Raymond to allow such a

thing to occur and be kept from doing his share of the fighting.

When Tom swung around to face the rear, and actually started to run

toward the oncoming foe, Jack knew what was expected of him. He must man

the gun, and prove how well he had learned his lesson when at school at

Pau and at Casso.

No longer could they expect to be guided by sounds. Their own motor

thundered so loudly that every other sound was deadened. They must

depend on eyesight alone to tell them when they were nearing the

oncoming Fokker craft. Perhaps the first indication they would have of

its presence would be the flash of its quick-firing gun, spattering

bullets around them like hail.

So Jack strained his vision to the limit. He was eager to discover the

enemy before they themselves were seen. Much might depend on who fired

first, in a duel of this kind.

Suddenly the gun began to bark after its own peculiar way. Jack believed

he had glimpsed something moving, and was sending forth a storm of lead

in the hope of a lucky hit that would crumple the other machine up and

put an end to that peril.

Tom held the course. He knew that every second was carrying the rival

airplanes nearer together--knew that possibly they were so headed that

if they continued to rush forward they might smash in a frightful

collision that would send both down thousands of feet to the earth.

It was a time for careful calculations and prompt action. Tom gripped

the controls and was ready either to swerve or to dip as occasion

demanded. Meanwhile, Jack was doing his best to riddle the advancing

Boche machine and its pilot.

There was no longer any difficulty in seeing just where the Fokker was,

for a constant flashing as her gun rattled betrayed its position

exactly. The flying lead was now whistling all about the two air service

boys but they did not know how close they sailed to death.

Then Tom swung smartly to the right. He dared not keep on longer in his

course lest he collide with the German craft. Just about the same

instant he realized that the Fokker was diving. There was something

queer about that manoeuvre. Tom had never known a French or an American

nor yet a British airman to adopt such a clumsy way of plunging so as to

avoid punishment.

Circling around he started back on a little lower level, looking for the

enemy. In making his latest volplane Tom had listened intently, hoping

to ascertain whether the motor of the enemy craft still throbbed

somewhere close by; but he heard not a sound to tell the story.

Just then, suspicious of the truth, he glanced down, and was just in

time to see a little flash of flame arise from the distant surface of

the earth. Then the awful truth broke upon both boys. They realized that

the German pilot had lost control of his machine, which had turned over

and over in its drop, finally crashing to the ground, and being

instantly enveloped in flames!
