yeah.....she took and me in and made me bacon & eggs and a vegemite sandwich. Can you hear can you hear me chunder ??
I believe it's particularly strong whoopie weed, from what I've been told, from a reliable friend, from research.....
Remember that the conveyor belt is subject to friction against the air that surrounds it:
As the conveyor belt starts sliding at a higher and higher speed in opposite direction to which the plane attempts displacement, it will create a huge air flow towards the plane and its wings and will actually help the plane to take off. The wheels will just lose traction to the belt.

I think forum software should make a difference,
when it obvious a word is properly used.
Like when a username is displayed.
I do not know if this has been fixed by now.
this happend when I quoted a fellow member of forum
who 'has got the wrong name':

Those who still maintain that the plane cannot take off, are overlooking a significant fact in that there is no *fixed* (or un-moveable) relationship between the plane (itself) and the belt, exactly the same as when on normal ground, unless the brakes are on of course.
The only such fixed relationship is merely between the 'contact patch' of the tyres with the belt (assuming no skidding takes place, here) so because the wheels are still entirely free to rotate, it matters not what the belt does, nor which way or even if it moves at all, anyway.
So long as there is no skidding between the tyres and the belt, the parameters stated in the question have been fully satisfied, whatever the belt does.
The plane's driving thrust is exactly the same as with any normal take-off (i.e. not provided via the wheels) and there is nothing to prevent the plane from moving forward *relative to the air*, and taking off. This is the principle of flight with fixed-wing aircraft.
"Devil's Advocate"!
To continually suggest that the bearings will get red-hot, or that the tyres will burst, or whatever, is IMHO just throwing up a smoke-screen, similar to the 'Rocket Expert' and his Canadian Guru, who knew all about this subject and gave us the "definitive answer" in the early days of this thread.
Rather interestingly, we don't appear to have seen anything further on this particular subject since then!

When I am sitting in the plane, I will see through the window that nothing is moving. The plane remains at the same position. If the belt flies, then the plane could fly on it.
Take off ???

Re: Re: Calling all clever people 🙂 What do you make of this?
That's the best answer so far.

Hi jh6you,

Why is there nothing moving? 😕 Nothing is fixed in relation to the earth. The plane will move forward. If you look through the window, you will see things moving faster and faster. Then everything will start to drop away as the plane takes off.

Who needs Einstein ? All the relitivity theories you ever wanted are right here on ......DIY Audio...
ha, every forum is the same with this question, its a nightmare. The problem is in the semantics of the question, not the science.

You are on the running machine and running at the exactly same speed at any given time with the rotating belt speed in opposite direction. (Net speed is zero between you and the belt). When could you catch your girl friend standing 1m away in front of your reach and teasing you? Probably, she would just laugh at you sweating like hell.

Hi jh6you,
Now that's easy!! To put it in the same frame as the original question, the running machine is on wheels free to move. I have someone pushing me from behind (thrust from engines, jet variety).
No matter what my feet do, my friend pushes me to her. Not being silly, I will stand there conserving my energy for the future. Now she is in trouble for teasing me and not understanding the laws of physics. 😉
