United (UA) 787-900 (789) flying LAX SYD made an emergency landing at Sydney (SYD) earlier today. All’s reported as ok but not much is know yet about what caused the pilots to declare the emergency in the first place.
Only note it here as the plane pic posted by Q earlier this week was of a UA 789.
