If you look at it from a purely theoretical point of view with no restrictions the plane will obviously fly. I'm not arguing the physics of whether or not the plane will move forward but I am questioning the results of a REAL LIFE experiment, with varying conditions being arbitrarily determined. Some people are or are not assuming certain conditions are being met -for example, how long is the conveyor and does the plane have to be on the conveyor when it achieves flight?
The vid proves the plane (or anything else being propelled with something other than the wheels touching the conveyor, like a jet engine) will accelerate forward. Did the plane in the vid have enough room on the treadmill to achieve enough forward velocity for the wings to generate lift? No. Provided there is enough conveyor distance for the plane to go fast enough, it'll take off WHILE ON THE CONVEYOR. If the Mythbsuters put their ultralight plane on a 10ft conveyor, it won't leave the ground until its forward velocity takes it WELL off the conveyor. 1000ft conveyor, sure it'll take off when it reaches enough forward velocity for the wings to generate lift - again, while it's on the conveyor.
When I said the plane wasn’t going to fly I did it based on how I assumed a real world experiment (such as the one the Mythbusters) might be set up. If they construct a 10ft conveyor, the pane will crash and burn. If it’s a 1500ft conveyor, it’ll fly. Do they have the budget for that, who knows? Physics doesn’t need a budget to be proven, but the Mythbusters experiment is dependent on how it is set up.
