There was a farmer that hit a natural gas line in IL a couple of years ago. Farmer was putting in a tile line and had a rep for the gas line company there to make sure they were all clear. I guess the tiling machine hit something, but the gas rep said that it was a rock or something and put tractor on front of the machine to help pull it through, unfortunately it was the gas line and the rep, farmer and the farmer's son perished in the explosion.
This one?

Didn't do a one-call to locate the line.
