Assuming that it matches the flight information, think that the ATS dudes are probably on the right track with the giant luminous ball on top of the Revel casino in Atlantic City:
The main scraper is approximately 720 feet tall and the ball with its 250,000 LEDs is said to be visible over a hundred miles in clear conditions. Also, the ball functions as a spherical display of sorts and as can be seen in other photos and videos it displays everything from solid colors to rapidly changing patterns, spinning colors and so on.
Looking at the YouTube video, there are a bunch of "spot on!"-comments in reply to earlier comments that are now deleted.
There are some references to this behavior on ATS too. Seems fishy. I think he knew what he was filming.
