Condensation trail from airplanes 😉
People having a bad time on the way to hopefully having a good time.
GM! Those are contrails(short for condensation trails) and they happen when hot gases from plane engines mix with cold air up there in the sky. Water vapor condenses(hence the name) and freezes into ice crystals that we see as these streaks ✌️
The CON in contrails is because they CON’d folks into believing it’s harmless….
