I saw that video also or maybe it was a similar one.  It looks like it was adulterated somehow...either by the poster or the source of the video.  There is a little glitch in the first frame where the object comes towards the building.  The positioning of the camera changes slightly but the gates in view don't move with the angle.  It looks like there was some editing done.  Overall though, I do think something is up with there not being any video of the plane.
