Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.

Simon Newcomb

Well, gentlemen, do you believe in the possibility of aerial locomotion by machines heavier than air? ... You ask yourselves doubtless if this apparatus, so marvellously adapted for aerial locomotion, is susceptible of receiving greater speed. It is not worth while to conquer space if we cannot devour it. I wanted the air to be a solid support to me, and it is. I saw that to struggle against the wind I must be stronger than the wind, and I am.

Jules Verne

Everyone loves to fly, and flying underwater is even better than flying in air because there are things around you.

But if we establish the working hypothesis that the UFOs are machines, we also have to assume the following: a) They are not built by human beings.. b) They are flying by means of artificial fields of gravity.. c) They produce high-tension electric charges in order to push the air out of their paths, so it does not start glowing, and strong magnetic fields to influence the ionized air at higher altitudes.

Hermann Oberth

The first real air-liner, carrying some five or six hundred passengers, will probably appear after or towards the end of the battle between fixed and moving-wing machines. And it will be a flying boat.

Oliver Stewart

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?

Joseph LeConte

One can get a proper insight into the practice of flying only by actual flying experiments. . . . The manner in which we have to meet the irregularities of the wind, when soaring in the air, can only be learnt by being in the air itself. . . . The only way which leads us to a quick development in human flight is a systematic and energetic practice in actual flying experiments.

Otto Lilienthal

I swam across the rocks and compared myself favorably with the sars. To swim fishlike, horizontally, was the logical method in a medium eight hundred times denser than air. To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. At night I had often had visions of flying by extending my arms as wings. Now I flew without wings. (Since that first aqualung flight, I have never had a dream of flying.)

Jacques Yves Cousteau

I want to paint the air in which the bridge, the house and the boat are to be found - the beauty of the air around them, and that is nothing less than the impossible.

Claude Monet

The cause of rain is now, I consider, no longer an object of doubt. If two masses of air of unequal temperatures, by the ordinary currents of the winds, are intermixed, when saturated with vapour, a precipitation ensues. If the masses are under saturation, then less precipitation takes place, or none at all, according to the degree. Also, the warmer the air, the greater is the quantity of vapour precipitated in like circumstances. ... Hence the reason why rains are heavier in summer than in winter, and in warm countries than in cold.

John Dalton

If you start lifting weights, you will expect to put weight on, as muscle is heavier than fat. But you have to look more at your body shape - you will get heavier - but you might get smaller and heavier at the same time, which is fine. And it doesn't really matter what you weigh as long as you are happy with your shape and size!

Victoria Pendleton

One way to understand light in the ocean of air is by flying it. Life in the air is an extension of perceiving.

James Turrell

There is nothing better in life than sliding down snow before flying through the air.

Shane McConkey

Your grandfather's coffin is heavier than you expect. Your father's coffin is heavier than you can bear.

Todd Lowe

Email is such a funny thing. People hand you these single little messages that are no heavier than a river pebble. But it doesn't take long until you have acquired a pile of pebbles that's taller than you and heavier than you could ever hope to move, even if you wanted to do it over a few dozen trips. But for the person who took the time to hand you their pebble, it seems outrageous that you can't handle that one tiny thing.
