Most importantly, it appear that you were thinking that the molecules on the overside of the top surface of the wing were somehow pulling up on the wing. This last post of yours, is, technically acceptable, You don't know how a wing works and now you are making pronouncements on what is technically acceptable? You are a k00k Perhaps there was just a misunderstanding. Well, since you misunderstand everything... Bertie |

It is something that simply does not happen. There is no sucking force. then think of it this way. Imagine a cross- section of the wing. The top surface of the wing forms a line. The air just above this line has lower pressure. The air below this line (inside the wing) has normal pressure. So the air below the line is pressing upward against it with more force than the air above is pressing down. I think you mis-understood me here. When I say the air below the line is pressing upward, I am not referring to the air pressing upward on the bottom of the wing. I am referring to the air _inside_ the wing pressing upward on the underside of the top surface of the wing. The air above the wing top surface has lower than normal pressure. The air inside the wing has normal pressure. So it presses upward on the top surface of the wing. This is lift generated by the top surface of the wing. What if your wing doesn't have any air in it? Bertie- Hide quoted text - - Show quoted text - It will still fly, of course. If you talk about the upper wing surface as a solid, with the air inside the wing under it, or if you talk about the whole wing as a solid with air under it, the principle is the same. You have lower pressure above the wing, and it contributes lift. |

You can also see from the falling line that you imply that there should be research to support my "theory", but there is no theory or all. I think we agree on this part. :-) |
