The treadmill question is poor in my opinion.
As it stands, there are no possible correct answers. Answers can only be provided by applying assumptions and constraints to the question which do not exist. It is entirely hypothetical and full of logical inconsistencies.
In my opinion, it is not a good fit for any SE site but especially this one. The only thing of relevance to aviation is that with enough airflow over the wings, the aircraft can fly - well duh!
The comments are already looking like those from a YouTube video and people with a poor grasp of physics (and this is what the question is about) are arguing all kinds of nonsense.
Does this really belong on here?
