Icarus "Shoot a plume of hot air laden with tiny particles into the upper atmosphere, where the temperature is, say, sixty below zero and the humidity is somewhat high. The air is suddenly unable to hold its water. Vapor condenses and clings to the matter in the jet’s plume. The air soon mixes and cools and the particles of water freeze. A contrail is born."
