No, I mean the teardrop shape required to produce lift. Air going over the top of the wing has to move further than under the bottom, producing low pressure above the wing, creating lift. Basic aerodynamics...

Planes don't really fly in the way we think. They're actually sucked into the sky. Same as a sail on a boat when you sail up-wind - you can only sail into the wind at 45 degrees towards it, where the shape of the sail acts like a wing causing the boat to be sucked up-wind rather than being blown down-wind.

That's cheating, nobody said anything about holding the wings up with arrows.

Well duh... how else does this work? There's a string too, attached to the moon.

Suction in physics is treated much like Centrifugal force. The idea of suction is basically a misunderstanding.



Almost any flatish section of wing will fly, provided that the leading edge is higher than the trailing, that would go if you reversed the airflow, providing you lifted the current trailing edge above the current leading edge. The current way around the shape is more efficient, but the opposite would fly if the other aspects of the shape of the wing were reasonable.

You mean like opening a freezer lets the cold out?

So "suction" is actually the inverse... really it's the high pressure pushing the wing upwards?

I did think about this once seeing the picture, after writing my last post.

Nah, it's the pixies shooting the little arrows, innit. They have to stand on the ground to shoot, so they can only shoot upwards, and the pressure of all them tiny arrows on the bottom of the wing makes it go up. Also, the equal and opposite force thing means that they also make the earth go away slightly as they fire.

I'm not sure how hot air balloons or zeppelins work, though, as the arrows would make lots of tiny holes, I think.

Twelve pages in and we finally have the answer - the plane cannot take off because the pixies will have been whisked away by the magical treadmill. No pixies, no arrows, no lift.

You mean "elevator"? What to vertical people transporters have to do with aeroplanes? Planes go forwards, not up. That's rockets.

If you put a rocket above a big sucking fan that could suck exactly as fast as the rocket shot out its fire, would the rocket take off? This would be a special fire-proof fan that matched its speed exactly to the thrust of the rocket. The rocket would already have its occupants, no snakes and they would have already had their in-flight meal. Pixies would be confined to the aeroplane problem previously stated and therefore not an issue.

Wouldn't the chopped up pixies start clogging the fan though?
