Many believe 'they' spray our skies. Nonsense. It's just a conspiracy theory. Those are contrails, lingering in high humidity. All predictable. Simple as that.
Friday - Yet more high humidity at flight level and due to a decaying weather-front there will be a lot of high-cloud and lingering contrails in the areas shaded dark blue. So expect hazy sunny skies even though your app might say ☀️.
Lingering contrails - predicted in advance.
@Shabba287@Petagna No-one sprays anything into the sky unless you live in your brainwashed world where you believe in chemtrails and believe the nonsense Dane spouts. Time to grow up and stop embarrassing yourself.
