Quasi,
You proved your fishing abilities in that "last thread" I can't mention. 😉
Poobah,
Al was only doing that for my own good. Right Al ?? 🙂 There are times I feel like he's watching me though.

Yeah... this chain thing deals with physics... that leads to truth etc...
We need a new speaker cable thread.

Re: qquestion on physics 🙂
Back to the original question:
Well, if it can be determined that one wheel is turning the other, then there must be a tension discrepancy between the upper and lower run of chain. So, there is a force on the chain.
The plane however, still won't fly.

As it was mentioned before, once everything is spinning at constant speed, one wheel isn't driving the other one anymore. They are just spinning on their own. And even then, there is tension in the chain.
Since you brought up the plane:
Yes, it will fly. I'm sure that they use parking brakes on them so they don't roll around the airport. So, if that plane is placed on the chain, the plane will move with the chain (along the flat part), and once the chain starts curving around the sprocket, the plane will keep moving forward and fly(assuming that it is going fast enough; if not, then the plane will just fall and crash).

Oh, but if you put a plane on the chain, then it's weight will induce a force upon the chain. In fact, the chain will be infinitely tensioned if it is to remain taut with the weight of the plane on it.

You don't actually secure the plane to the chain. You just place it there, and it will be launched off the chain at the first curve (sprocket).
Either way you do it, there will be tension in the chain.

I meant just the plane's weight bearing down on the chain. Not attached to the chain.
Oh, and for it to take off, the wheel speed will not equal the belt speed. Zing.

This thread is very similar to the sprocket / chain system in question......it just goes round and round.
Anyway not even the perpetual motion argument works here because the links will try to fly off at a tangent. Removing all losses associated with friction will not remove all forces, i.e. the forces used to retain the chain links. These forces will eventually slow the system down ......unlike this thread.

Hi Quasi,
I am so, so sorry for what I did earlier. 
Now that evil little mouse will be hunting for me!
