Original Note:
The image claims contrails can be distinguished from "chemtrails" by their length. This is false: both images show contrails. Their length depends on the humidity of the surrounding air. In humid air, contrails last longer because they cannot evaporate as they do in dry air. https://earthobservatory.nasa.gov/images/78154/the-evolution-of-a-contrail
