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.— Lord Kelvin
Successful Flying Machines quotations
If you want to fly, give up everything that weights you down.
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.

When you can measure what you are speaking about, and express it in numbers, you know something about it.
The way to fly is to go straight up .
. . Such a machine (the helicopter) will never compete with the aeroplane, though it will have specialized uses, and in these it will surpass the aeroplane. The fact that you can land at your front door is the reason you can't carry heavy loads efficiently.
What good are wings withou the courage to fly.
I saw at once that I had only to rise in my machine, fix my eyes upon the castle, fly over it and speed directly across to the French coast. It seemed so easy that it looked like a cross-country flight. I am glad I thought so and felt so.

Can you imagine any better example of divine creative accomplishment that the consummate flying machine that is a bird?

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.
People who fly into a rage always make a bad landing.
Man studied birds for centuries, trying to learn how to make a machine to fly like them. He never did do the trick; his final success came when he broke away entirely and tried new methods.
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.
It had never gotten old for him, flying.
Never gone boring. Every engine start was a new adventure, guiding the spirit of a lovely machine back into life; every takeoff blending his spirit with its own to do what's never been done in history, to lift away from the ground and fly.
If you can't fly, then run, If you can't run, then walk, if you can't walk, then crawl, but whatever you do, you have to keep moving forward.

There is a thrill of vulnerability at all airshows.
There is no way of making everything completely safe. When the machines are being thrashed to capacity and the pilots are flying at their limits to dazzle, things are bound to go wrong sometimes. There have been some historic disasters, but the danger is a part of the attraction.
Eagles don't fly with pigeons.
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.
He bores me. He ought to have stuck to his flying machine. On Leonardo Da Vinci
By his machines man can dive and remain under water like a shark;
can fly like a hawk in the air; can see atoms like a gnat; can see the system of the universe of Uriel, the angel of the sun; can carry whatever loads a ton of coal can lift; can knock down cities with his fist of gunpowder; can recover the history of his race by the medals which the deluge, and every creature, civil or savage or brute, has involuntarily dropped of its existence; and divine the future possibility of the planet and its inhabitants by his perception of laws of nature.

I am an enthusiast, but not a crank in the sense that I have some pet theories as to the proper construction of a flying machine. I wish to avail myself of all that is already known and then, if possible, add my mite to help on the future worker who will attain final success.
Swords, Lances, arrows, machine guns, and even high explosives have had far less power over the fates of nations than the typhus louse, the plague flea, and the yellow-fever mosquito. Civilizations have retreated from the plasmodium of malaria, and armies have crumbled into rabbles under the onslaught of cholera spirilla, or of dysentery and typhoid bacilli. Huge areas have bee devastated by the trypanosome that travels on the wings of the tsetse fly, and generations have been harassed by the syphilis of a courtier. War and conquest and that herd existence which is an accompaniment of what we call civilization have merely set the stage for these more powerful agents of human tragedy.

That has been the sole purpose of our flights. This one flies higher, that one faster. But now we will make ourselves at home. We will forget the machine, the tool. It is no longer complex; it does what it is supposed to do, unnoticed. And through this tool we will find again the old nature, the nature of the gardener, the navigator, the poet.
