Can a Plane on a Treadmill Take Off?

My post is not contrary to Thomas', it reinforces his comment. My statement
is a further rebuttal to the statement thomas was responding to.

On the contrary, the problem clearly states that the conveyor is moving
at the speed that the plane is moving (but in the opposite direction).

The statement "the conveyor is moving at the speed that the plane is
moving" (the one you say the problem states) is a very different statement
from "which always reduces the plane's forward movement to zero" (the
statement Thomas responded to).

How is your post contrary to Thomas'?

You made two replies to my own post, which are in contradiction with each
other.

Furthermore, if you intend to reinforce a person's post, I suggest you not
begin the post with the words "on the contrary".

Bob,

On the contrary, the problem clearly states that the conveyor is moving at
the speed that the plane is moving (but in the opposite direction).


Huh? The OP was saying "If you have a conveyoer which always reduces the
airplane's movement to zero", to which I said "the original question doesn't
say that". What does you statement have to do with what I said, let alone it
being "contrary"?

I did not say that, either. I said the conveyer was moving at the speed
the airplane is moving, but in the opposite direction. I did not say
that the conveyer reduced the airplane's movement to zero, an
impossibility short of tethering the airplane.

With respect to what?

I'm not responding to anything in specific, but to the mere fact that
this thread has gone on so long. You can answer all your questions by
answering "with respect to what?" for all movement issues, and realizing
that the airplane flies (or not) by moving with respect to the
surrounding air.
