Hi all. Why contrail doesn't form on high altitudes? In game it forms somewhere on 8km, and stop to form above 14km. In real world, contrail appears somewhere at 8km and disappears if aircraft (or rocket) is flying above ~15km. As far as i know, contrail is formed when jet exhaust over-saturate surrounding air, and then as it cools, it turns into solid state (crystals). There is also a lot to read about that in internet. But why it disappears on high altitude i cant find. My guess is that because of low pressure, ice crystals cannot form. What do you think?
