I trust Jim Cash.
I lived in So Calif from 1964 to 1993.
Saw lots of static tests done by Rocketdyne in Box Canyon at the west end of the San Fernando Valley where I lived.
The area where this ‘contrail’ came from is at sea—there are no ‘airport runways’ out there as far as anyone I know in So Calif thinks.
This was a missle—probably from a submarine.
China? N Korea? Iran? Who knows, but we are being fed a total line of CRAP by this administration.
Well, that fits in seamlessly with everything else this administration has said and done.
