World's Deepest-Diving Unmanned Submarine Lost
XenonOfArcticus writes "Kaiko, the world's deepest-diving submarine was lost in in late May off Japan, after it snapped its tether as a typhoon approached. Kaiko entered the record books in 1995 by diving 36,008 feet to the bottom of the Challenger Deep - the ocean's deepest point."
I don't know anything about this submarine (though I did RTFA), so I'm puzzled by its design. You mean to tell me that these things aren't made to be radio-controlled? That once the cable connecting it to the mother ship is cut, it's bye-bye Charlie? That's silly for a multi-million dollar piece of equipment. These folks should learn from NASA about redundant control / communication systems.
Have EVDO, will travel.
