Z-Mac,

That story may not be too far from the truth. When I liven in the Middle East I saw a magazine article about a Japanese bulldozer, a Komatsu I believe, that they used to clean out small coastal harbors in Japan. It was run underwater by remote control. When I came back to the States I mentioned this to the guys where I now work. The story was met with a amount of snickering and the usual, "Well, here's another overseas story". I sent an email to Komatsu, mentioned the article, and they sent me back a picture and the story about the tractor. Of course none of the men ever appologized but I never got snickered at again.
