Remarks: UNITED 840 Departs back to LAX but unfortunately she had to return back to Sydney after just taking off from Sydney within an hour because landing gears could not retract and hence had to dump over 150 tonnes of fuel circling around the seas of Australia before returning back. As you can see on the front landing gear the landing gear doors are open. My 700th photo on the Jetphotos Database!!
Remarks: After already going tech for a few days, N105UA operating UA6872 arriving back at Sydney after pouring out quite a lot of black smoke (from Engine no.1) on takeoff and off the coast, and then dumping fuel. No emergency was declared and it seemed like a perfectly normal landing, at least it made for an interesting afternoon and an opportunity to catch UA landing in nicer light!
