I'm still curious how they know which house blew up first? Quoting: Anonymous Coward 13998309
Yeah, it looks like the center of the blast is between the two houses that were totally obliterated. I could see one house disappearing with only a scorch mark from an internal gas leak, but not two.
Being that nobody officially wants to blame gas, neither the ntsb nor the gas company, there must be some behind the scenes arm twisting to decide who is going to lie about it and blame the gas or come up with a pure alternative fairy tale.
Gas companies have to have good lawyers just because of the nature of the beast. They would tend to hang onto the "our investigation is not complete" approach as long as possible rather than "it wasn't us" this early in the game if they weren't sure.
If the gas company was able to recover an intact meter or two, they could easily determine whether or not enough gas went through it to cause this much destruction.
They have a record from the last monthly reading for every house in the neighborhood. A meter involved in a house with a major appliance leak would show an unusually high reading since the last reading compared to the others. This ain't rocket science.
So either no intact meters were recovered to prove it wasn't gas related, which I doubt, or there is some serious effort being made to spin a plausible not gas related story or some serious effort to get somebody to lie that it was gas related going on behind the scenes.
