I don’t think it could be anything but a missile.
What I question is the trajectory.
Did it fly over the US? If so I say it was either a mistake/inadvertent launch or not a US missile.
I don’t believe we would knowingly test a missile over US territory. I’d bet on it.
There was a Freeper here posting on another thread that ACTUALLY saw this thing... he said it was a plane.
And, another plane on the very next day made a similar contrail.
I believe him... non-story to me from here on.
It was headed out to sea, we would not launch off the coast of California with no notice and no notams and our military did not make a mistake, lie about it, or “lose” a missile
This posibility is dismissed by the similar Atlantic launch a couple of days or so later to show vulnerability of both coasts.
Only a COINCIDENTAL inadvertent launch on each coast could vaguely explain theses two events in tandem.
Also the “warning” is watered down if missiles come from the USA instead of just miles off the Chinese or Russian shorelines, providing the THREAT that China put in play.
