Ben Sandilands ran an article on this incident...
Virgin Australia 777 in sudden brief dive near Melbourne Airport
....although most of the commentary focussed on the ATsB blurb and in particular the word "
guests"??:
Virgin Australia is assisting the Air Transport Safety Bureau with an investigation of an international flight at Melbourne International Airport on Thursday 15 August. The aircraft landed without incident after the crew disengaged the autopilot and manually flew the aircraft. There was no danger to the aircraft or guests at any time.
You're right though not much commentary on here about anything much at the moment!!??
