If you look close there is asmall chance the craft may be a stealth plane of somesort, but if so its is very unsual it would be hovering over the city.
Filmers comments: Hovering object in sky over downtown Atlanta. Object was about 20feet wide.
1. We were on the 15th floor of a high rise building in Atlanta. We were working.
2. We were looking out the window and it was significantly above a 200ft Ferris Wheel.
3. Various accounts in the office: a kite, a stealth bomber, a drone, an airplane & a weather balloon.
4. It hovered mostly stationary with occasional changes in elevation.
5. Curious. 6. Went to upload the video we just took and it was gone. Multiple witnesses posted their experience on Reddit. (link above)
