everything is possible
in santiago every year we see airplane shows . we know in some ways the usual airplane trail.
The odd facts here are:
- this lasted on the sky for a couple of hours
- this looked the same from several different places
- this trails kept their shape unlike the usual ones who are deformed after a few minutes
i leave the answer to the experts. i just want to know the explanations
