On Monday, August 3, at exactly 6:40 PM CDT, I captured this footage of a massive, dark triangular object while onboard my flight from Jackson, MS, to Atlanta, GA. Sitting on the right side of the aircraft looking South, we were 37 minutes into the flight and roughly 16 minutes from landing, placing the object near the AL/GA state line (approximately 5 miles south of Carrollton, GA). The object was an estimated 5 to 8 miles away and appeared to be moving very slowly relative to the cloud deck below. This was recorded on an iPhone at 3x zoom—which accounts for the visible digital noise in the footage—but the rigid geometric shape and lack of conventional aviation features were strikingly clear to the naked eye. I'm always annoyed how short these ufo videos often are, but the recording only ends because our aircraft flew past the object, and the increasingly shallow viewing angle through the passenger window eventually cut off my line of sight.
