I received my baptism into this kind of work the third time I went out over the lines, and I would recommend it to any one who is hankering for excitement. You are not only apt to be attacked by hostile aircraft from above, but you are swept by machine-gun fire from below. I have seen some of our machines come back from this work sometimes so riddled with bullets that I wondered how they ever held together. Before we started out on one of these jobs we were mighty careful to see that our motors were in perfect condition, because they told us the "war-bread was bad in Germany."

One morning, shortly after I joined the squadron, three of us started over the line on our own accord. We soon observed four enemy machines, two-seaters, coming toward us. This type of machine is used by the Huns for artillery work and bomb-dropping, and we knew they were on mischief bent. Each machine had a machine-gun in front, worked by the pilot, and the observer also had a gun with which he could spray all around.

When we first noticed the Huns our machines were about six miles back of the German lines and we were lying high up in the sky, keeping the sun behind us, so that the enemy could not see us.

We picked out three of the machines and dove down on them. I went right by the man I picked for myself and his observer in the rear seat kept pumping at me to beat the band. Not one of my shots took effect as I went right under him, but I turned and gave him another burst of bullets and down he went in a spinning nose dive, one of his wings going one way and one another. As I saw him crash to the ground I knew that I had got my first hostile aircraft. One of my comrades was equally successful, but the other two German machines got away. We chased them back until things got too hot for us by reason of the appearance of other German machines, and then we called it a day.

This experience whetted my appetite for more of the same kind, and I did not have long to wait.

It may be well to explain here just what a spinning nose dive is. A few years ago the spinning nose dive was considered one of the most dangerous things a pilot could attempt, and many men were killed getting into this spin and not knowing how to come out of it. In fact, lots of pilots thought that when once you got into a spinning nose dive there was no way of coming out of it. It is now used, however, in actual flying.

The machines that are used in France are controlled in two ways, both by hands and by feet, the feet working the yoke or rudder bar which controls the rudder that steers the machine. The lateral controls and fore and aft, which cause the machine to rise or lower, are controlled by a contrivance called a "joy-stick." If, when flying in the air, a pilot should release his hold on this stick, it will gradually come back toward the pilot.

In that position the machine will begin to climb. So if a pilot is shot and loses control of this "joy-stick" his machine begins to ascend, and climbs until the angle formed becomes too great for it to continue or the motor to pull the plane; for a fraction of a second it stops, and the motor then being the heaviest, it causes the nose of the machine to fall forward, pitching down at a terrific rate of speed and spinning at the same time. If the motor is still running, it naturally increases the speed much more than it would if the motor were shut off, and there is great danger that the wings will double up, causing the machine to break apart. Although spins are made with the motor on, you are dropping like a ball being dropped out of the sky and the velocity increases with the power of the motor.

This spinning nose dive has been frequently used in "stunt" flying in recent years, but is now put to practical use by pilots in getting away from hostile machines, for when a man is spinning, it is almost impossible to hit him, and the man making the attack invariably thinks his enemy is going down to certain death in the spin.

This is all right when a man is over his own territory, because he can right his machine and come out of it; but if it happens over German territory, the Huns would only follow him down, and when he came out of the spin they would be above him, having all the advantage, and would shoot him down with ease.
