@Will2Power @Breaking911 IDK, haven't looked at my phone today. Probably ground control, followed by inatentive taxiing by one of the crews. Atlanta is awful, terrible quality in personnel there so it's mostly the airports' fault.
Everyone gets a little bit of blame, if you're astute then you know everyone will screw up and almost kill you. Once every few months I'll have a near-hit because of someone screwing up in their own flight planning, or an inattentive controller putting a putt putt in front of me while I'm speeding in on an approach. Every time I just laugh and enjoy the quiet while the other guy stresses out contemplating his mortality
Things have gotten MUCH worse across the board
