This was his result.
He thinks it was far out to sea, behind/northwest of UPS902. He does believe he saw UPS902 far to the south of the object he was viewing, because he specifically compared that contrail, which was obviously a jet liner, to this object, which was NOT obviously a jet liner.
He said that typical jet airliner contrail, in comparison to the one he videotaped, was like "comparing a tree to an ant." The contrail he was filming was nothing like the other jet airliner contrail he had in view at the time to the south.
Thanks for the confirmation.
