When Lisa first saw this sky, she thought it would be a good quiz for cloudspotters; 'how many different kinds of clouds can one identify?' And it appears that the sky agreed by way of a visible question mark, as spotted here over Bellport Bay, Long Island, New York, US.

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.
