Original Note:
Contrails are caused by cooling and condensation of the jet exhaust water vapor. This process takes time and thus appeals slightly behind the aircraft. This is also a common occurrence visible in industrial areas where there is combustion and exhaust venting from smokestacks. https://acp.copernicus.org/articles/13/10847/2013/acp-13-10847-2013.pdf
