What happened? House fill up with Natural Gas and then a spark (from AC/ coffee pot, etc) blew the house up...or did a BIG propane tank (500 gallons+) blow up? Jeez! Here I am wanting to get a Propane tank and hook it up as dual fuel to my NG generator.
I don’t think liquid propane really blows up. I suspect this was similar to a natural gas leak. The house fills with gas (and air) and, just like in an automobile cylinder, a spark is applied resulting in an explosion.

That was during the Carter I years.
