I have to burst your bubble, but consistent symmmetric turns in the contrail are indicative of a jet airliner.
It is the wing-tip vortices which cause this effect.
If you look at the photos or video, there are two distinct trails.
Missiles and ICBMs don’t have two distinct trails.
I saw one trail. Understand wing tip vortices, but aren’t there usually two in opposite directions? I saw one clockwise twist, for example from a cheap spin-stabilized SCUD type islamonut piece of low tech garbage. Don’t they have those that they can fire out of a shipping container?
Or was I seeing it wrong?
