I did. Saying “everyone” when it’s just probably one person is not usually ok. It’s fine to say if you interpreted the comment in a certain way, and ok to be the outlier. But assuming your interpretation applies to others more broadly than it does, is counterproductive.

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?
