Guys these aren't chemtrails. They are formed through the injection of water vapor into the atmosphere by exhaust fumes from a jet engine. If there is sufficient mixing between the cold upper tropospheric air and the hot exhaust gases to produce a state of saturation, ice crystals will develop. Like clouds. there is absolutely nothing harmful about these clouds.
