Plane on a treadmill poll...

[speedminded]

ski planes don't just sit still and take off, they gain speed on the water/snow then take off.... you're right it has nothing to do with the wheels... but everything to do with speed... a plane must gain ground speed to create wind speed which causes the plain to lift...


i want you to get on a treadmill with a kite and put on some roller blades... or run if you'd like... see how long it takes you to get that kite in the air....

i promise it won't lift.. even if you put a jet pack on your back.. until you gain enough SPEED to create LIFT

Why do you think the plane will not gain ground speed? What's preventing the engines from creating thrust and propelling the plane forward?

He thinks that the treadmill, rolling in reverse, can prevent a plane from moving forward. THAT is where he has an error in logic.

ohhh, so you mean those doubting should think about if the plane will actually move forward before debating how wings create lift and all that nonsense?

Yes! If they can understand the concept that the plane WILL move forward no matter what the treadmill is doing, they can then logically draw the conclusion that forward movement will lead to acceleration. That acceleration will approach take-off speed and the plane is in the air...
