When I was little, I was so curious to find out how planes actually move on ground...I thought the landing gear's wheels are connected to some engines; so the wheels are actually...propelling the aircraft on the ground, just like cars. I considered the idea of using the engines to move the plane on ground as being downright crazy

But the idea of motorized landing gear wheels is not crazy anymore....it seems I was a visionary CHECK THIS.

Hee he hee

And if we do choose not to abandon our dreams as grown ups, we are regarded as being crazy/weirdos.
