Web30 aug. 2024 · Depending on how moist the air is and the temperature of the surrounding air, the contrails can last for just a few minutes before dissipating. Or they could last for quite a while longer; a general rule of thumb is that the more humid the air is, the longer the vapor trails are going to last. WebContrails are just condensation vapor (from the combustion of fuel) leaving the back of the engine. As the humid air exits, it starts to cool and form small particles of ice crystals in the air which makes this line of cloud. You could say contrails are a type of cirrus cloud. Unfortunately the aircraft is too high and the photo too low-res to ...
