Well, one of 'em was looking sort of interesting in the middle of the screen at about 1:10, but indeed they look like short lived contrails illuminated by the setting sun... But I got a laugh out of your reaction to them. I imagine they looked a lot better in person than on film. By the way I do appreciate it when people take the time to film their entire sighting rather than a few seconds as you said in the video, also.

Take care.
