"The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It'll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn't been reusable."

"What I didn't know was I was deeply attracted to the big space."

"The future is vastly more exciting and interesting if we're a spacefaring civilization and a multi-planet species."

"Rockets are cool. There's no getting around that."

"My partner and I are looking at several locations on Park Avenue South and Midtown for a new restaurant space."

"We are aware only of the empty space in the forest, which only yesterday was filled with trees."

"I would like to fly in space. Absolutely. That would be cool. I used to just do personally risky things, but now I've got kids and responsibilities, so I can't be my own test pilot. That wouldn't be a good idea. But I definitely want to fly as soon as it's a sensible thing to do."

"I would have taken whatever hand I was dealt. Space was it."

"Common sense steps in here and says: Separate the parts you want to be mobile from the parts you want to be inert. You have seen the result, and I know many have the skill to apply it."


"It becomes a giant's task to compute the result when the effect of cross seas, wind at all angles and ever varying force, arched surfaces, head resistance, ratio of weight to area, and the intelligence of the guiding power crop up."


"If you direct your attention to the position of a bird with regard to the wave surface, it will speedily be noticed to be nearly always on the rising side or face of the wave and moving apparently at right angles to the wave's course, but really diagonal to it."


"And from a poise at this station the plane may swoop down, at great disadvantage if close to the back of the wave, at various slopes and directions till it cuts into the air that is being raised by the face of the following wave, which again enables it to resume its velocity."


"The plane is simply abstracting the power stored in the wave by a distant gale, and using it to counteract gravity. And if the work be continued long enough, or a multitude of planes be continually drawing on the reservoir of power, the wave must inevitably be flattened."


"The most ordinary conditions for observing sailing birds are then the wind and sea are both aft."


"As to the effect of the wave on the air, we will suppose the water to be quite flat and the air motionless, a heavy undulation comes on the scene, it has to pass, so it pushes the air up with its face, letting it fall again as its back glides onwards."


"The closer the bird is to the surface of the water, the firmer and more inelastic is the uplift of the rising air. The bird appears to almost feel the surface with the tip of its weather wing."


"Used as kites, these rigid stable aeroplanes are superior to the very best cellular kites I can make; they are lighter, pull harder per square foot, attain a greater angle of elevation, and have fewer parts."
