Can anyone explain?? One with trail other no trail ?

I think everyone else has replied. So I will too 🤣 Different altitudes, different atmospheric conditions.

Different flight levels.

You pretend you’re asking an innocent question but you’re not. You’re asking a question you can research yourself with very little effort to fuel a narrative that these con trails are in some way malicious. Clearly this is a conspiracy you believe cos who the fuck films planes…

Knob head 🤣🤣🤣🤣

Different altitudes, different conditions. Can anyone explain how they convinced people to film/photograph the sky and post on social media? That’s the bigger question.

Different heights. So different temperatures affecting condensation.

Different altitudes so one will produce condensation and the other wont. Or any of another half dozen simple explanations. Chemtrails? Really Gareth?

Nothing new, vapour trails are as old as flying. The American bomber formations could be seen from 100’s miles in WW2. Notice the ones at lower height aren’t leaving trails

Yes, atmospherics, air pressure and humidity.
