If you run on a treadmill you feel no air moving because you’re stationary.If you run on the road you feel air because you’re moving forward.

Very wrong
You feel no air because you arent moving foreward, because your propulsion (your feet) is relative to the ground, meaning your feet push you foreword, so on a tradmill, that force is negated
On a plane, the foreword motion is provided by the engines, which is NOT relative to the ground. The engines will always push foreward, because there is NO mechanical connection between them and the ground
Dumb it down ever further:
The motion of a plane has only to do with air being pushed away from it by the engine, causing a reaction, moving the plane foreword. The motion of the ground has NOTHING to do with that
If it was a car, it would be different. It wouldnt move, because there IS a connection between the carls propulsion system (the wheels) and the ground
