Short version…

Those “streams” are clouds. Planes make clouds.

Keywords: condensation, water vapor, temperature change

Contrails—unless you are at an air show, and the jets are releasing pressurized water from tanks on their wings to create artificial trails.

There are also untold conspiracy theories one can look up!

(I’m gullible, I believe most of them and try to balance them with non conspiracies)
