If the frictional force of the river to the floats is the same or greater than the force of the thrust then the plane will remain still or continue to flow backwards. The plane must overcome the frictional force of the water the same as it would have to overcome the frictional force of the bearings in the wheels. The "speed" of the river would still not matter, it's the "frictional force" that must be overcome by the plane.

It isn't actually. The myth is that the treadmill is moving backwards at the same speed as the plane is moving forwards through the air (plane's movement is measured relative to the air.) Once the plane reaches the right airspeed, it can take off, no matter what the ground is doing beneath it.

Mudchair, the myth says the treadmill is going the opposite direction as the plane, Do you think there is one person in this world that would believe a non powered plane will magically move forward and take off when on a treadmill moving backwards?
You are the one confused, maybe watch some more videos on the subject and you will understand better.

i think its just a joke...pretty funny though, totally snapped us out of our 4 hour argument on the problem =D
-
you're doing it wrong
-
The point of the experiment is that the plane should not be moving.

Did you notice that the plane hit the end of treadmill? maybe if there was more space for the plane it would take off? you could see it gain speed over the treadmill, thus if more space would equal the take off?

And actually the math comes out to: 3mph - -3mph = 6mph (the wheels will spin at 6mph), the plane moves forward at 3mph (relative to the objects not on the conveyor, and the conveyor moves at -3mp relative to the objects not on the conveyor. Georgia Tech, son.

Good stuff! LOL
I think a lot of people have missed the humour in this video.

its common sense! it would take off. friction produced by the wheels is dramaticaly less than the thrust provided by the engine/engines!

No shit Sherlock.

It will work, the wheels dont provide the thrust, the propeller/jet does therefore the wheels will spin, the wrong way but it will still take off
