The opposite of a contrail is a “distrail”. When a jet flies through a high cloud the introduction of the extra water from the exhaust is sufficient to cause the cloud to precipitate, leaving holes or trails. This is a satellite image over Texas.  Holes form when the plane is climbing or descending through the cloud.  The longer trails form when a plane flies at about cloud height for a while.

Here’s another example from North Texas, and a picture of what these hole shaped distrails look like from below.
