A classic example of a distrail, also known as a dissipation trail, when a clear path is formed through a cloud by the passage of an airplane. It develops when the heat from an aircraft's engine warms and evaporates supercooled cloud droplets. This distrail, along with a nearby contrail, was spotted over Montmeló, Barcelona, Spain.
