I went back through and read some more of your posts. You seem to go way outside the original question. The question is worded in a very trickey way. The wheels of the plane have nothing to do with forward motion.
What someone needs to do here is get a 1:18 car. Attach a model rocket engine to the car. Then get the car on a treadmill that is spinning fast enough that the car wheels are turning but the car is staying in place, then light the rocket engine. Record the whole thing and post the video in this thread.
As you say the original question is worded in a “tricky way” . Your own interpretation will dictate how the belt operator responds to the plane. Read it one way and the plane takes off. Read it the other and it does not.
But you and I are not discussing the original question so we don’t have to worry about that.
What you said in post #124 was “No matter how fast the belt moves the plane will still take off."
Do you stand by that statement after reading my post #89?
