Lights are elaborate on craft.. reminiscent of a diamond flickering in the sunlight.. always near the airportCraft sits perfectly still and flashes multiple colors( like a diamond flickering in sunlight ) near the flight/landing track the planes take going into the airport.. I stay near the Falcons stadium.. the planes come in and make a huge U-Turn from heading eastbound toward the south.. at first I assumed that it was a a helicopter.. but i've seen helicopters leave from near Grady hospital and there is usually just one yellowish light that is on. These lights on this craft flash in color from white, to red, to blue, to yellowish, to aqua.. i've seen this same craft a few times in the distance as the planes come in on their track toward the airport.. Hopefully i'm not misidentifying this this craft.. it could be a helicopter with an elaborate light fixture that monitors the planes landing and has lights to make sure its visible to all planes coming in?.. I will try to send a video next time I see this.. i've seen it a few times.. I've also witnessed a satellite ! in passing.. I have a keen eye and i'm able to discern what can be explained and what can't..
