Yah. Me too. I was busy assembling my new treadmill from bigbox mart and missed the show. What fun. Not.

I bet the plane is going to be even harder to assemble.

Busted. I love how they phrased the question so they could bust it. If the myth had been "the plane can take off" it would have been confirmed.

So, why is there still an argument?[/horrible tailposting]

Wtf? The plane was moving forward...so the treadmill wasn't equal to the plane? Well duh, it's not stationary as the original question seemed to suggest, of course it will take off, it will just take the wheels longer to get up to speed.

It was moving backward relative to the ground at the same speed the plane was moving forward relative to the ground.

That was the trick in the trick question- it seems to suggest that the plane will be stationary, but doesn't actually say so.

No. The wheels actually move twice as fast.

Right. "Plane can't take off": Busted. "Plane can take off": Confirmed.

Right. This is usually a question: "Can a plane on a treadmill take off?"
But since they are the mythbusters they phrased it so they could score a "bust."

Also (separate point here) they phrased the scenario to specify "ground speed."

They ran the treadmill at takeoff velocity (25 mph). I wonder what the result would have been if they ran the treadmill at the plane's maximum velocity.

If enough viewers complain about their testing methods, they will revisit the myth. Sometimes they're wrong. I'd say this one is still wide open!

The same thing. For axle friction to noticeably slow the plane would require a treadmill moving at unimaginable speed. Now that I think of it, a treadmill moving fast enough to slow the plane might even cause enough of a wind-tunnel effect to counteract that friction.
