Yes, please cite specific claims from the video, with time reference. (It is mercifully short, under one minute in length...which is a plus).
I can say with no risk of error, though....just looking at the "still" image that YouTube provides in the preview, I see perfectly ordinary contrails.
I also can assert this since I am completely aware that "chem"trails are a myth, they are not (as presented) technically feasible, would be virtually useless even if that are what is being claimed by "chem"trail believers due to their altitude above the ground, and...
....finally, besides being myth, they are often perpetuated by unscrupulous individuals who know that they are a hoax, but carry on anyways, either for profit, attention or both.
