Towards the aerodrome I walked behind the towering line of moonlit hangars, beyond which I could hear the murmur of the engines "warming-up." Between two tall sheds I stumbled, and came on to the wide grassy expanse where stood my machine surrounded by busy mechanics.

The engines opened out with a terrifying burst of noise. I collected my map-case and my torch, and walked round to the front of the machine. I faced the two shining discs of the whirling propellers and gingerly advanced between them to the little rope-ladder which hung from the small door in the bottom of the machine. Up this ladder I climbed, and found myself in the little room behind the pilot's seat. I knelt down and shone my torch on the bomb-handle, the bomb-sight, and on the twelve fat yellow bombs that hung up inside the machine behind me. Then I walked forward till I came to the cockpit, where sat the pilot on a padded armour-plated seat, testing the engines. I let down my hinged seat beside him, and sat with my feet off the ground. I put away my pencil and note-book and chocolate, and examined the different taps and the Very light pistol, and began to adjust the petrol pressure of the engines, which was indicated by little dials in front of me.

I was about seven feet off the ground now, sitting up in the nose of the machine, feeling very small and helpless, with the two great propellers screaming on either side a foot behind me, at 1700 revolutions a minute, and I felt very much like a lamb going to the slaughter.

Minutes slowly passed. I was itching with impatience. I longed to start so that I might have something to do to occupy my attention.

The pilot blew a whistle. The pieces of wood in front of the wheels were pulled away by the mechanics. The pilot's hand went to the throttle, and we moved slowly across the aerodrome. The front engine roared out, he turned round and faced the wind, with the lights of the flares behind us.

On went the engines with a mighty throbbing beat. At once we began to roll across the ground. Faster and faster we rushed. Below streaked the flare-lit grass as we swept onward at a fearful speed. The hangars were just in front of us. I sat, feet off the ground, with my left hand on the padded edge of the cockpit, nervous and apprehensive.

Then slowly, surely, the machine left the ground and began to move upwards, and soon cleared the top of the hangars. Below lay the moonlit sweep of the dim forests, the curving hills and the deep-shadowed ravines, looking pale and unreal in the ghostly radiance.

In front of us the phosphorescent finger of the height-indicator slowly crept to 1000 feet. The speed-indicator wavered between 50 and 55 miles an hour, and the dials which recorded the petrol pressure on the engines obeyed faithfully my alterations to the little taps at the side.

Above us was the wide expanse of the starlit sky and the cold moon. We soon found that flying at night was like moving through a dimmer daytime sky. Though the airman is hidden from the ground, yet below he can see a detailed panorama, a little more limited in range than that of noonday, but not much less distinct. This is, of course, on a clear night of ample moon. On dark and misty nights the change is very much greater. As we flew on we realised that the task was not going to be so difficult as we had imagined.

For a time I felt too nervous to look over the side, as I always have felt, flying by day or night, until the preliminary dread of a wing falling off which has ever haunted me has grown less poignant. Then I began to look over the side, and the love of experience and excitement battled and pressed down the feelings of dread.
