Which makes perfect sense with how planes move. But 21 pages later
Nope, in their experiment they pulled the conveyer at 25mph in the opposite direction and the plane went forward at 25mph to take off. Meaning the wheels were spinning like it was going 50mph. Not the same here. They were matching the planes takeoff speed, not the wheel speed.
A plane with wheels can't advance down a runway unless the wheels spin. They have to spin faster for it to go faster. Same on the treadmill, it can't advance down the treadmill unless the wheels spin at rate faster than the treadmill spins them.
Same as a car on a treadmill, it can't advance forward on the treadmill unless the wheels spin fast enough for it too. Doesn't matter where the propulsion is coming from, how strong the thrust is, etc. The WHEELS have to spin faster or it doesn't move forward. Period!!!
You are too stuck on thrust, where it's coming from ,etc that you are forgetting the wheels still have to spin at rate that let's them advance forward and allows the plane to advance forward. If the conveyer matches then they cant.
