Original Note:
When at a high altitude, 30k to 40k feet, the air is less than 0 degrees in temperature, around -40 to -60 degrees within the range. The hot jet fuel mixes with cool air which then forms crystals that look like "chem-trails", when actually, it's just a vapor trail. https://www.britannica.com/story/what-is-known-and-not-known-about-contrails https://www.earthdata.nasa.gov/topics/atmosphere/clouds/tropospheric-high-level-clouds-observed-analyzed/contrails
