"When I reached the nineteen-thousand-foot level, which was about midday, the wind was so severe that I looked with some anxiety to the stays of my wings, expecting momentarily to see them snap or slacken. I even cast loose the parachute behind me, and fastened its hook into the ring of my leathern belt, so as to be ready for the worst. Now was the time when a bit of scamped work by the mechanic is paid for by the life of the aeronaut. But she held together bravely. Every cord and strut was humming and vibrating like so many harp-strings, but it was glorious to see how, for all the beating and the buffeting, she was still the conqueror of Nature and the mistress of the sky. There is surely something divine in man himself that he should rise so superior to the limitations which Creation seemed to impose – rise, too, by such unselfish, heroic devotion as this air-conquest has shown. Talk of human degeneration! When has such a story as this been written in the annals of our race?

"These were the thoughts in my head as I climbed that monstrous, inclined plane with the wind sometimes beating in my face and sometimes whistling behind my ears, while the cloud-land beneath me fell away to such a distance that the folds and hummocks of silver had all smoothed out into one flat, shining plain. But suddenly I had a horrible and unprecedented experience. I have known before what it is to be in what our neighbours have called a tourbillon, but never on such a scale as this. That huge, sweeping river of wind of which I have spoken had, as it appears, whirlpools within it which were as monstrous as itself. Without a moment's warning I was dragged suddenly into the heart of one. I spun round for a minute or two with such velocity that I almost lost my senses, and then fell suddenly, left wing foremost, down the vacuum funnel in the centre. I dropped like a stone, and lost nearly a thousand feet. It was only my belt that kept me in my seat, and the shock and breathlessness left me hanging half-insensible over the side of the fuselage. But I am always capable of a supreme effort – it is my one great merit as an aviator. I was conscious that the descent was slower. The whirlpool was a cone rather than a funnel, and I had come to the apex. With a terrific wrench, throwing my weight all to one side, I levelled my planes and brought her head away from the wind. In an instant I had shot out of the eddies and was skimming down the sky. Then, shaken but victorious, I turned her nose up and began once more my steady grind on the upward spiral. I took a large sweep to avoid the danger-spot of the whirlpool, and soon I was safely above it. Just after one o'clock I was twenty-one thousand feet above the sea-level. To my great joy I had topped the gale, and with every hundred feet of ascent the air grew stiller. On the other hand, it was very cold, and I was conscious of that peculiar nausea which goes with rarefaction of the air. For the first time I unscrewed the mouth of my oxygen bag and took an occasional whiff of the glorious gas. I could feel it running like a cordial through my veins, and I was exhilarated almost to the point of drunkenness. I shouted and sang as I soared upwards into the cold, still outer world.

"It is very clear to me that the insensibility which came upon Glaisher, and in a lesser degree upon Coxwell, when, in 1862, they ascended in a balloon to the height of thirty thousand feet, was due to the extreme speed with which a perpendicular ascent is made. Doing it at an easy gradient and accustoming oneself to the lessened barometric pressure by slow degrees, there are no such dreadful symptoms. At the same great height I found that even without my oxygen inhaler I could breathe without undue distress. It was bitterly cold, however, and my thermometer was at zero, Fahrenheit. At one-thirty I was nearly seven miles above the surface of the earth, and still ascending steadily. I found, however, that the rarefied air was giving markedly less support to my planes, and that my angle of ascent had to be considerably lowered in consequence. It was already clear that even with my light weight and strong engine-power there was a point in front of me where I should be held. To make matters worse, one of my sparking-plugs was in trouble again and there was intermittent misfiring in the engine. My heart was heavy with the fear of failure.
