I was approaching an airport the other day, Seoul I think, There was an airbus on final. I followed him in. On short final he went around. Climbed to about 1000 ft agl and proceeded to fly thru a mountain pop out into the next valley and continue his 2 mile circuit thru another mountain and out over the bay before turning final and repeating the same circuit. Rinse and repeat. Artificial “Intelligence”, I think not.
