a 744 2 wks had a problem in flight due to a large banging sound and the cabin filling wlth dust or mist,which had to return back to Sydney due to structual integrity concerns(VH -OED who sister aircraft VH -OEC had a large crack in the crown which was found during a D check in Syd HM),and now another aircraft had to make a return due to an engine malfucntion,this is becoming a concern with Syd HM only being shut down less than a year ago,what nexted.
BA did a similliar thing over ten yrs ago with shutting down it's main base and then returning it's maint back in house,because the outsourcing option didn't work,you would of thought QF would have learned from this mistake
