It was while this mysterious talk with the soldier still stirred in Bert Smallways' imagination that the most astounding incident in the whole of that dramatic chapter of human history, the coming of flying, occurred. People talk glibly enough of epoch-making events; this was an epoch-making event. It was the unanticipated and entirely successful flight of Mr. Alfred Butteridge from the Crystal Palace to Glasgow and back in a small businesslike-looking machine heavier than air--an entirely manageable and controllable machine that could fly as well as a pigeon. It wasn't, one felt, a fresh step forward in the matter so much as a giant stride, a leap. Mr. Butteridge remained in the air altogether for about nine hours, and during that time he flew with the ease and assurance of a bird. His machine was, however neither bird-like nor butterfly-like, nor had it the wide, lateral expansion of the ordinary aeroplane. The effect upon the observer was rather something in the nature of a bee or wasp. Parts of the apparatus were spinning very rapidly, and gave one a hazy effect of transparent wings; but parts, including two peculiarly curved “wing-cases”--if one may borrow a figure from the flying beetles--remained expanded stiffly. In the middle was a long rounded body like the body of a moth, and on this Mr. Butteridge could be seen sitting astride, much as a man bestrides a horse. The wasp-like resemblance was increased by the fact that the apparatus flew with a deep booming hum, exactly the sound made by a wasp at a windowpane.
