Chapter 16

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. It Was hung in a peculiar manner in order to minimise the complex vibration that even a moderate wind produced, and for the same reason the little seats within the car--each passenger remained seated during the voyage--were slung with great freedom of movement. The starting of the mechanism was only possible from a gigantic car on the rail of a specially constructed stage. Graham had seen these vast stages, the flying stages, from the crow's nest very well. Six huge blank areas they were, with a giant "carrier" stage on each.

The choice of descent was equally circumscribed, an accurately plane surface being needed for safe grounding. Apart from the destruction that would have been caused by the descent of this great expanse of sail and metal, and the impossibility of its rising again, the concussion of an irregular surface, a tree-set hillside, for instance, or an embankment, would be sufficient to pierce or damage the framework, to smash the ribs of the body, and perhaps kill those aboard.

At first Graham felt disappointed with these cumbersome contrivances, but he speedily grasped the fact that smaller machines would have been unremunerative, for the simple reason that their carrying power would be disproportionately diminished with deminished size. Moreover, the huge size of these things enabled them--and it was a consideration of primary importance--to traverse the air at enormous speeds, and so run no risks of unanticipated weather. The briefest journey performed, that from London to Paris, took about three-quarters of an hour, but the velocity
