The answer to your second question is probably no. I have never seen anybody small enough to fit down a hole the diameter that a pole digger would make.
All I know is that I was told from early childhood that if I started digging a hole in my yard in Ohio and dug it deep enough, I would end up in China. I'm surprised nobody has yet dug a tunnel to smuggle in goods from China and bypass customs and import duty.
Why should we go around the outside of the globe, when we can take a shortcut through the middle?
Maybe we could set up vacuum tubes to suck products back and forth from one side of the world to the other. Maybe people, too. <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
