Contrails are formed by water vapor being super-cooled as it passes through a jet engine. The frozen vapor is quickly melted by the sun. This phenomena only occurs above 35000 feet, and the humidity and barometric pressure has to be just right. The lines seen crisscrossing our skies today are not contrails. They are man-made clouds, most likely used for weather modification...what many people call "chemtrails".
They are formed by aircraft at altitude. Period. The moisture content in the air at that altitude and whether that air is warm or cold determines whether or not there are contrails.
These are military aircraft, and in the two videos you provided they are obviously able to turn the trails off and on. You say "chemtrails are figments of the imagination". You are a liar, either lying to yourself because you can't handle the truth, or lying to aid and abet a crime against humanity.

Partially incorrect. Old radial engine aircraft also left contrails.

Of course they were military aircraft. THERE WERE NO CIVILIAN AIRCRAFT CAPABLE OF FLYING AT THAT ALTITUDE.
Contrails are a function of moisture in the engine exhaust, air temperature, and altitude. Air temp and humidity varies at higher altitudes.
Believe what you want. You obviously have your mind made up, and I'm not going to waste my time explaining again.
