Gliders, sail planes, they're wonderful flying machines. It's the closest you can come to being a bird.
Heavier-than-air flying machines are impossible.
In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science, whatever the matter may be.
The demonstration that no possible combination of known substances, known forms of machinery and known forms of force, can be united in a practical machine by which men shall fly along distances through the air, seems to the writer as complete as it is possible for the demonstration to be.

I imagine a future aircraft, which will take off vertically, fly as usual, and land vertically. This flying machine should have no moving parts. This idea came from the huge power of cyclones.
Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?
It may be that the invention of the aeroplane flying-machine will be deemed to have been of less material value to the world than the discovery of Bessemer and open-hearth steel, or the perfection of the telegraph, or the introduction of new and more scientific methods in the management of our great industrial works. To us, however, the conquest of the air, to use a hackneyed phrase, is a technical triumph so dramatic and so amazing that it overshadows in importance every feat that the inventor has accomplished.
Every flying machine has its own unique characteristics, some good, some not so good. Pilots naturally fly the craft in such a manner as to take advantage of its good characteristics and avoid the areas where it is not so good.
I've always been amazed by Da Vinci, because he worked out science on his own. He would work by drawing things and writing down his ideas. Of course, he designed all sorts of flying machines way before you could actually build something like that.
There is no basis for the ardent hopes and positive statements made as to the safe and successful use of the dirigible balloon or flying machine, or both, for commercial transportation or as weapons of war.
It is apparent to me that the possibilities of the aeroplane, which two or three years ago were thought to hold the solution to the [flying machine] problem, have been exhausted, and that we must turn elsewhere.
To the possible enquiry as to the probable character of a successful flying machine, the writer would answer that in his judgment two types of such machines may eventually be evolved: one, which may be termed the soaring type, and which will carry but a single operator, and another, likely to be developed somewhat later, which may be termed the journeying type, to carry several passengers, and to be provided with a motor.
Can you imagine any better example of divine creative accomplishment that the consummate flying machine that is a bird? The skeleton, very flexible and strong, is also largely pneumatic - especially in the bigger birds. The beak, skull, feet, and all the other bones of a 25-pound pelican have been found to weigh but 23 ounces.
He bores me. He ought to have stuck to his flying machine. [On Leonardo Da Vinci]
Let us hope that the advent of a successful flying machine, now only dimly foreseen and nevertheless thought to be possible, will bring nothing but good into the world; that it shall abridge distance, make all parts of the globe accessible, bring men into closer relation with each other, advance civilization, and hasten the promised era in which there shall be nothing but peace and goodwill among all men.
The popular mind often pictures gigantic flying machines speeding across the Atlantic carrying innumerable passengers in a way analogous to our modern steam ships. . . it seems safe to say that such ideas are wholly visionary and even if the machine could get across with one or two passengers the expense would be prohibitive to any but the capitalist who could use his own yacht.
Victor Vigny: It is like the old fairy tale. The boy saves the princess; they fall in love. He invents a flying machine - along with his dashing teacher, of course. They get married and name thier firstborn after the aforementioned dashing teacher. Conor: I don't recall that fairy tale from the nursery. Victor Vigny: Trust me, It's a classic.
We Americans claim to be a peace-loving people. We hate bloodshed; we are opposed to violence. Yet we go into spasms of joy over the possibility of projecting dynamite bombs from flying machines upon helpless citizens.
May there not be methods of using explosive energy incomparably more intense than anything heretofore discovered? Might not a bomb no bigger than an orange be found to possess a secret power to destroy a whole block of buildings-nay, to concentrate the force of a thousand tons of cordite and blast a township at a stroke? Could not explosives even of the existing type be guided automatically in flying machines by wireless or other rays, without a human pilot, in ceaseless procession upon a hostile city, arsenal, camp or dockyard?
I have had the feeling that a properly constructed flying-machine should be capable of being flown as a kite; and conversely, that a properly constructed kite should be capable of use as a flying-machine when driven by its own propellers.
My objective is and has been for years to make the lightest and most compact flying machine that would carry me at 25 or 30 miles per hour for 10 minutes or a quarter of an hour. Current events show this is not at all an ambitious project. Want of an elementary knowledge of oil machines baulks me and causes much misdirected effort. I doubt my ability to acquire that knowledge, and feel like a fireman trying to hew out a donkey pump.
One: There is a low limit of weight [of about] 50 pounds beyond which it is impossible for an animal to fly. Two: The animal machine is far more effective than any we can hope to make. Three: The weight of any machine constructed for flying, including fuel and engineer, cannot be less than three or four hundred pounds. Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?
We don't have the capability today to put a human being in space of any kind, shape or form, which is absolutely, totally unacceptable when we got the greatest flying machine in the world sitting down at Kennedy in a garage there with nothing to do.
