Someone said to bring this thread back up and say I told you so.
So, I told you it would fly.

So, is any of this renewed interest due to last night's airing of a "Myth Busters" episode where the airplane vs the conveyor was tried in models and real A/C with a pilot?
I guess their conveyor was not as magic as the one we worked with previously in this thread, huh?
I was surprised that the pilot actually thought he would not take off... but he did.
It is easy to see the difference between the myth guys approach and the MAGIC CONVEYOR we had to contend with. It is an apples to oranges comparison and as interesting and fun as the myth guys episode may have been it DID NOT have the attributes with which we struggled and its results are not valid as regards the discussion here. It was trivial to predict the outcome considering their conveyor did not have the requisite acceleration to take advantage of the inertia in the wheels of the plane and so forth.

I am going to quote myself from page one on Nov 8, 2006 just to say "Told you so".
It is simple physics and it amazes me that so many people don't get it.
THE WHEELS DO NOT PROPEL THE AIRCRAFT, IT DOES NOT MATTER HOW FAST THEY ARE SPINNING ON A CONVEYOR BELT. OBVIOUSLY IF IT WAS A CAR, THE CAR WOULD NEVER MOVE.
Here is a new one for you guys:

Re: Mythbusters/airplane/treadmill
For anyone that missed the EXACT wording of the problem as originally posted on TBN, here it is:
a plane is standing on a movable runway( something like a conveyor).as the plane moves the conveyor moves but in the opposite direction.the conveyor has a system that tracks the speed of the plane and matches it exactly in the opposite direction.
the question is
will the plane take off or not?

Re: Mythbusters/airplane/treadmill
The big argument was the use of the words:
matches it exactly in the opposite direction

I'm confused again. Why are the airplane tire's rotating with this magical conveyor belt???
