Both comments were significantly downvoted at the time of my comment, which was what I was referring to. The original comment explicitly mentioned "relative airspeed", which I thought was pretty clear (it's the speed of the plane relative to the air that matters).

I think calling it a "common misconception" is also assuming a lot.

I teach people how to fly. Trust me when I say that this is an extremely common misconception. It's one of the concepts students have the greatest difficulty wrapping their heads around.

Do these people never use treadmills or trains?
