So, your variable states that if the plane was going faster than the belt on the treadmill, then yes it could take flight, (assuming it had enough power to propel itself to whatever speed it normally needs for takeoff on a runway, + the speed at which the treadmill is spinning at) Agreed, but that's not what the circumstances and plan are. Read the article. It states that the treadmill will spin at the SAME speed as what the plane would normally become airborne on a runway, therefore the plane would be stationary with no airflow under its wings. That's why and how it WOULDN'T lift off. Get it?
