re: #94 LudwigVanQuixote

FWIW, I’m not buying the contrail explanation either. The plume extends right almost to the horizon for one thing, which means the visible base of the “contrail” would be an enormous distance away (200+ miles) if it were coming from a high altitude aircraft in horizontal flight. Its density and width at the point are not consistent with that kind of distance compared to the top of the plume.
