A Quote by Otto Lilienthal

All flight is based upon producing air pressure, all flight energy consists in overcoming air pressure. — © Otto Lilienthal
All flight is based upon producing air pressure, all flight energy consists in overcoming air pressure.
The light dove, cleaving the air in her free flight, and feeling its resistance, might imagine that its flight would be still easier in empty space.
That there is a Spring, or Elastical power in the Air we live in. By which ?????? [elater] or Spring of the Air, that which I mean is this: That our Air either consists of, or at least abounds with, parts of such a nature, that in case they be bent or compress'd by the weight of the incumbent part of the Atmosphere, or by any other Body, they do endeavour, as much as in them lies, to free themselves from that pressure, by bearing against the contiguous Bodies that keep them bent.
The true method of discovery is like the flight of an aeroplane. It starts from the ground of particular observation; it makes a flight in the thin air of imaginative generalization; and it again lands for renewed observation rendered acute by rational interpretation.
I was in the Air Force and was a boom operator (in-flight refueling). I got my comedy start in the Air Force.
Drive over to the nearest airport, and enroll in flight classes. You will experience the joy of freedom in the air above, as you study the mechanics of how this is made possible by understanding the construction, the laws of motion, the air that can provide lift when it is moved by propulsion through the air, and stay above the gravity pulling the airplane back down to earth.
I shot an arrow into the air, It fell to earth, I knew not where; For, so swiftly it flew, the sight Could not follow it in its flight. I breathed a song into the air, It fell to earth, I knew not where; For who has sight so keen and strong, That it can follow the flight of song? Long, long afterward, in an oak I found the arrow, still unbroke; And the song, from beginning to end, I found again in the heart of a friend.
The scientist states that pressure is exerted outwards in all directions equally, whereas natural pressure (e.g. air pressure) is exerted inwards from all directions equally.
There should be a minimum on the air pressure but not a maximum. Every game, they're taking air out of the footballs I'm throwing, and I think that's a disadvantage for the way that I like them prepped.
I leave no trace of wings in the air, but I am glad I have had my flight.
Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.
Waste Management was based in Chicago, but I lived in Ft. Lauderdale and for 10 years had to commute to work - catch the 5 P.M. Sunday flight to Chicago and the midnight return flight on Friday.
I've always thought flight was fun and wanted to write about flight, and I knew a lot of househusbands who were having a really bad time with it. I thought flight might perk up a marriage here or there.
Books are meat and medicine and flame and flight and flower steel, stitch, cloud and clout, and drumbeats on the air.
There's a huge amount of pressure on every astronaut, because when you get right down to it, the experiments that are conducted on a space flight, or the satellites that are carried up, the work that's to be done, is important and expensive work, and you are up there for a week or two on a Space Shuttle flight. The country has invested a lot of money in you and your training, and the Space Shuttle and everything that's in it, and you have to do things correctly. You can't make a mistake during that week or two that you're in space.
Pressure? What pressure? Pressure is poor people in the world trying to feed their families. There is no pressure in football
I don't feel pressure in a negative way. I like pressure. I feel excitement and calm at the same time. No pressure, no diamonds. I want pressure: pressure creates drama, creates emotion.
