. Water vapor - a by-product of combustion in a jet engine (there, in fact, taken the humidity). Formation of condensation trails depends on the height and composition of the surrounding atmosphere -. Mainly on the temperature and vapor pressure »

Thus, it turns out that this track - sort of a long cloud that eventually dissipates and becomes part of cirrus clouds.
