Hmm.
From memory, there was an example a couple of years ago where a gas leak in one spot allowed the gas to travel along the underground pipe, come up somewhere else some distance away, a commercial building as I recall, and go off there.
Took authorities a while to figure out what had happened.
Anyone else remember that?
I wonder if something like this could have happened, where an ignition at one point traveled along the pipeline gas-air mix ourside the pipe and lit up the gas leaking up in other homes.
Just working from memory.
