You should try to sell an Antifa cap and see if they take the same stance. Do it under a different account though.

It has nothing to do with temperature. Think dew point.
Do you think regular clouds are not at the same temperature as the air around them?
Wrong. It is condensation. Commercial pilotfag here. Depending on the current atmospheric conditions you may get very little visible exhaust, or you may get a lot.
As the aircraft approaches, you can clearly see that it is coming from the jet exhaust.
>Has everything to do with temperature
Sorry, but that's simply not true. Have you ever watched a plane in landing configuration on approach pass through humid air? Just the pressure differences caused by the wing and the control surfaces alone can cause water vapor to become visible.
At altitude the temperatures are well below zero, so what you are looking at are actually ice crystals. They can take a very long time to dissipate, which is perfectly normal.
They are at different altitudes, with differing dew points for those parcels of air.
