Maybe its a coincidence, but I shot VH
-OQE day before yesterday at Singapore, arriving (presumably) from London with hydraulic problems (the undercarriage doors remained extended during final and landing).
Long shot that this is the reason why it may have been delayed.
I don't think that is a long shot at all. The aircraft that operates QF10 which arrives early in the morning usually operates QF9 which departs in the afternoon. Instead yesterday 747 ferried down from Sydney to operate QF9.
Often (I can't remember exactly which days) an A380 will ferry down from Sydney in the morning and operate QF93. It could be VH
-OQE was originally due to fly to Sydney and then ferry down to Melbourne. With the possible issue in Singapore maybe there was an aircraft swap which had VH
-OQE fly direct into Melbourne albeit many hours late and operate QF93.
This is all speculation but it at least makes some sense to me. Either way yourself, some spotter in Los Angeles and I had some interesting photo opportunities.
