Occasionally a jet plane, especially if ascending or descending, will pass through a much drier or more moist layer of atmosphere which may result in a broken pattern to the contrail, with it appearing in segments rather than in one continuous plume.
The net should be full of sky photos from decades gone by showing what I am seeing daily , they are not.
