I want to know from real pilots on here how long can a real contrail last? I'm seeing these contrails/chemtrails last 5 and 6 hours. They are grids in the sky and get bigger and bigger until they become a huge cloud. You can also see a rainbow effect around the sun when looking up at the edge of the sun. It looks like a small amount of oil floating on the water. I know what produces a contrail. I just want some verified answers from real pilots on this site. Thanks for your time!!!

The contrails phenom is largely controlled by the temperature and moisture content of the ambient air, and I think is also effected by certain qualities of the fuel being burned.

Hi, BADBURD.
