    Well that could be problematic.

    So I’m curious now… what conditions cause the contrails? Certain temps, humidity, wind speed? I would think very humid cold air but that’s just a guess.

      In answer to your question: yes. Humid cold pure air. By pure, I mean no contaminates until the hyrdrocarbons from the jet fuel are emitted into that pure, moist air. To form a droplet, a nucleus is needed. The hydrocarbons of the jet engine exhaust provide that nuclueus.
