The single trails depart form typical aircraft chemtrails with their curious cork-screw appearance mostly at the beginning and end of each trail — Later, we see an almost identical aerosol deployment of 3 trails suggesting they’re released by drones, ground-based artillery or from cargo aircraft such as C-130 with a service ceiling above about 22,000 feet where normal cirrus clouds are formed.
