re: Can this 747 take off?

I don’t think this argument, which requires you to disregard friction, the impracticality of a 747 treadmill, or any other number of real world conditions, was designed to get people thinking about lift, negative feedback loops, or the speed of the conveyor.
It was designed to think about how the plane will move forward because it doesn’t act against the treadmill.
I think people are afraid to admit their first guess of the plane not taking off was wrong, so they’re bogging the issue down with semantics.
