At low altitude we cannot see contrails, so, if you see a non persistent trail, this is a chemtrail like persistent chemtrails. ***** There is no difference between persistent and non persistent wake, if you want to know if there are Chemtrails. You must observe the altitude! However the poisoners are cunning and they use different types of trails, including the non-persistent. In this way they deceive people like you.
