I neglected to say that this so-called aviation expert has zero credibility. I remember the cockamamie explanations for TWA flight 800 about sparks in the tank causing the explosion. It was a missile. That’s what people saw. That’s what it was. Just like in this case.
So, this was just a jet, nothing to worry about here! Just move along comrade.
BOHICA!
As was the case with TWA 800, regardless of what it is the explanation is basically not fit for public consumption. The really scary part is that one plausible explanation has this being a botched attack on the U.S. mainland. If that’s what it was this isn’t the only time it will happen. Someone intended for this thing to be seen and I suspect that whoever was supposed to see it know what they saw and the significance of it.
There's a meteor shower every year starting at about that time ~ and there are some "clinkers" in the mix. Just a matter of time until one hits a plane.
