The aircraft involved was taking off I'd heard ... not sure what exactly happened with the gear but the runway surface was gouged at the intersection ... repair crew hustled up but repair truck broke down enroute to scene (!! Murphy again !!) ... runways 16R/25 not available for approximately 1 hr 45 minutes.
Several 747s landed 16L in the meantime - QF580 was the only one to divert (to MEL with M.E.L. limits???)
