And I was being too frivolous on a sad subject. It sounds like a natural gas leak explosion or water heater. Both very bad.
It’s OK. In today’s world we find out and comment on things we are emotionally disconnected from and it’s easy to be less than sensitive.
BTW, I am familiar with water heater explosions. They are bad, but not this bad. I wouldn’t have heard a water heater explosion at this distance but this shook my house and shop heavily.
