That’s cool STZ, I’ve heard about this footage last week, but have not had time to see it yet. ….90% of my time on the forum is on my tablet, and that doesn’t have flash, so I can’t watch youtube, unless there is a direct link. But I’m on my lap top this morning and just watched the plane footage. It’s not the wing tip light, they ruled that out on the footage. My only assumption is that it could be, ( if they were flying over an ocean) , oil wells off in the distance. They have fire on the top of each well .
I don’t think it would be a blimp due to the speed of the airliner, the blimp wouldn’t be able to run side by side to the jet at that speed, also I don’t think it’s another commercial plane due to the lack of blinking running lights.
Here is footage that are oil wells from the Gulf of Mexico a few years back, I’m sure you have seen this footage, its made the rounds on UFO shows:
