Maybe it is a slow news day.
Absolutely it was a slow news day, what a crock of ****e!
Firstly it didn't land at 11.30am in Brisvegas, it was about 6.30am (7.30am Sydney). Secondly there was no engineering problem!
As someone else pointed out about the unforecast headwinds, they decided to divert abeam Brisbane as they were going to be short for holding at YSSY and then diversion to YBBN. They landed at YBBN, got some fuel, and left. Nothing more, nothing less...
