Invisible Chemtrail Aircraft/ Orb captured on video?

Athough this clip is short (taken while in traffic), it is similar to many other such objects captured on video that have no visible aircraft in front of the contrail/plume. This is the second one in a row that I witnessed, yet only captured this one on video. These usually have a short plume and travel in one direction, as opposed to others I’ve captured that fall from the sky in a corkscrew pattern before gaining control and shooting off to one side in a straight line, or ones that simply spiral down to the ground. The one captured in this video has been shown in other videos (not cpatured by me) to have a glowing orb in front of the plume as well. Although, in addition to no visible aircraft, there was no visible orb in front of the plume.
