Actual Condensation trail, showing the difference between this and aerosol "chemtrails". They BOTH exist, they are two different things. This plane stopped leaving a chemtrail and started leaving only a CONtrail.
Great comparison footage on this high traffic , heavy spray morning ! If you're unfamiliar with this phenomenon, please search "Clifford Carnicom" and look for his research/presentations regarding this topic aka "aerosols".
