The video shows what looks like three bright streaks and two dim streak move across the sky. At one point there's a flash. Suggestions given are a much of meteorites, or some kind of advanced technology craft, possibly alien.
However, I think it might just be the landing lights of a plane, smeared out by the long exposure of the old night camera. Something like an MD-80 perhaps, with the triangle of big lights, and two smaller lights.
Or a C5
I mocked up the scene in Aftereffects, creating a very similar effect with image persistence from frame to frame.
