Argue this....WHAT FORCE ACTS AGAINST THE ENGINES!!!!!???
I like the Ice analogy.
A plane on skates will take off. A car will spin in one place.
At work I crush buildings into tiny little concrete pieces. Then we use a long uphill conveyor to stockpile the crush. Sometimes round rocks end up on the conveyor. The round rocks just roll forever at the bottom of the convayor.
Sometimes the rocks come loose at the top of the conveyor, and they roll down to the bottom of the belt as if the convayor was standing still.
OMG google works. First hit for conveyor airplane. Tones, read it, then admit stupidity.
