When the Sleeper Wakes by H.G. Wells

For a while, as Graham went through the passages of the Wind-Vane offices with Lincoln, he was preoccupied. But, by an effort, he attended to the things which Lincoln was saying. Soon his preoccupation vanished. Lincoln was talking of flying. Graham had a strong desire to know more of this new human attainment. He began to ply Lincoln with questions. He had followed the crude beginnings of aerial navigation very keenly in his previous life; he was delighted to find the familiar names of Maxim and Pilcher, Langley and Chanute, and, above all, of the aerial proto-martyr Lillienthal, still honoured by men.

Even during his previous life two lines of investigation had pointed clearly to two distinct types of contrivance as possible, and both of these had been realised. On the one hand was the great engine-driven aeroplane, a double row of horizontal floats with a big aerial screw behind, and on the other the nimbler aeropile. The aeroplanes flew safely only in a calm or moderate wind, and sudden storms, occurrences that were now accurately predictable, rendered them for all practical purposes useless. They were built of enormous size -- the usual stretch of wing being six hundred feet or more, and the length of the fabric a thousand feet. They were for passenger traffic alone. The lightly swung car they carried was from a hundred to a hundred and fifty feet in length.
