Explanation: What created this giant X in the clouds? It was the shadow of contrails illuminated from below. When airplanes fly, humid engine exhaust may form water droplets that might freeze in Earth's cold upper atmosphere. These persistent streams of water and ice scatter light from the Sun above and so appear bright from below. On rare occasions, though, when the Sun is near the horizon, contrails can be lit from below. These contrails cast long shadows upwards, shadows that usually go unseen unless there is a high cloud deck. But that was just the case over Istanbul, Türkiye, earlier this month. Contrails occur all over planet Earth and, generally, warm the Earth when the trap infrared light but cool the Earth when they efficiently reflect sunlight. The image was taken by a surprised photographer in the morning on the way to work.

Contrails? I know Chemtrails when I see them!

Looks like the X-Men’s version of the Bat Signal.

That’s pretty cool. I’ve seen many contrails, but have never seen that happen.

Chemtrail obviously. I saw a jet just today going across the sky. As the jet flew from north to south, the contrail behind it dissipated.... as usual.
Anyone stupid enough to believe the chemtrails being sprayed into our atmosphere is just contrails is stupid enough to also believe the 2020 election was not stolen by the Marxist left and that the globalist elitists are not out to kill us.
To: ProtectOurFreedom
I spent many a day in the sunshine, fishing, riding bikes playing sports, never saw a contrail that lasted for more than a few seconds until after the year 2000. The condensation evaporated, just like it does today. What they are leaving behind are Chemtrails.
