Einstein was not over thinking light, as he was looking for those things.
And, reading beyond what is there in plain sight, is over thinking.
It's simple, what state does a plane need to be in to take off. If you think beyond that basic factor, it is over thinking.

You two make me as embarrassed of my fellow Ags in the same way as the people who think it won't (under normal conditions) take off.
I'm messing with you, NA.

NA,
The speed necessary for take off is far short of infinite.
Infinite is moot.

im sorry NA
how bout einstein was just a little more awesome than you?

What I don't understand is why some of you engineers didn't apply this logic and mathematically test this hypothesis. Using the conditions given in my scenario, you could have estimated the speed at which the conveyor would need to be moving to prevent the plane from taking, if it wouldn't at all.
You could then use these results to very nice refute the original myth mathematically.

If a conveyor belt is set to the same speed as required for a plane to takeoff, in the opposite direction, will the plane take off?
If they both start at the same time, of course it will take off, but no one is debating that. No one with a brain anyways.
The conveyor is moot.

$$$
and
Mythbusters did it
How much money does it take to pull out your calculator and look up some values?

Please calculate the necessary take off velocity in furlongs per fortnight.
The conveyor is moot.
The conveyor is moot.
marcel marceau is also moot
marcel marceau is mute
actually he died IIIhorn so techincaly he is moot
I stand corrected!
Did they bury him in a glass box?
yes, but it was such a quiet ceremony that nobody heard it
What exactly are you debating, nine?
'We will now observe 84 years of silence for the beloved deceased.'

That the way the myth is stated is misleading. In the same fashion those stupid trick questions like "If a bull eats alot of chocolate, will it make chocolate milk."
will it?
That's udderly ridiculous.

test this hypothesis
Sorry, NA. Read too fast and missed the word mathmatecally.
Somebody on a page way back did the free body diagram with the equation.
It's that simple. Plug in some numbers and boom.
NA!
I did not know bulls produced milk
He was steer'd the wrong way.

That is a seminal concept.
SERIOUSLY!!???? This thing is still ****ing going!!!!!!!!!! It flys. End of story. No friction. Not trick question. Not poorly worded. IT ****ING FLYS!!! Let this damn thing die!!!!

I'm going to take you back to physics 101:
The only force that the conveyor is applying to the airplane is dynamic friction. Dynamic friction is found by multiplying the Normal force (which on a level surface would be equal to the airplane's weight) by the coefficient of dynamic friction. Varying the speed of the conveyor in no way factors into the equation.
If anything, the increased wheel speed heats the bearings, makes the material more maeliable and decreases the coefficient of friction. Also, as the plane burns fuel, its weight decreases, lowering the frictional force. Any way you look at it, there is no setting that will prevent the plane from moving forward and taking off.
NA and IIIHorn

I'm pretty sure I know my physics. You just indicated that you missed the entire point of my post.
Um, the way the myth was worded was pretty clear to me.
ttt for yellowpot
