How can you be so wrong about something so simple and common? The sheering is due to high altitude winds. That’s all it is. It’s been proven over and over again on here, but some people refuse to get it.
After that, insult how long they’ve been registered.. One side has evidence and multiple images of other contrails and we even know what plane this was. The other side has a 10 second edited clip that still looks just like a contrail.
Nice going guys.
Your total lack of knowledge, coupled with your gullible penchant for repeating what other total ignoramuses spout make you the fool of the month.
High altitude shearing of a contrail would rapidly erase the entire trail, fading it like a sheet, not a dense stripe.
