EX A380/ Atiuta
Are you serious?
I can understand if they were somewhere enroute, but continue on three engines just after departing??
"They may have wanted to continue and land further down route once the fuel allowed landing at below max landing weight."
They had just taken off from SYD heading for DBX, so maybe the Alice or DRW was a consideration? Plenty of A380 spares there as opposed to returning to SYD
