I can't believe that people are still not getting this! Even funnier was a post a couple of days ago that called those who DO get it dumb
It has already been explained excellently several times over so my effort is doomed to failure but I can't help myself.
1 The wheels are rolling freely
2 the belt can move as fast as it likes, it makes no difference to the plane what the wheels are doing.
3 the propeller on the front of the plane pulls it forwards, the belt is going the other way so the wheels turn faster but the plane keeps
accelerating until it takes off. Thats all there is to it.
If the friction of the wheel bearings or the weight of the plane was enough to counter the thrust of the engine and keep the plane stationary then the
the egine is shagged and the plane not airworthy anyway, it would not even take off from a normal runway.
