I'd heard of one the recent plans for it, involved it being craned onto a barge off the side of CLK, then taken around to the waters off Hoi Ha in the Sai Kung country park, and carefully lowered (dumped!) there to become a reef/diving attraction.
One of the airbus skippers who lived out there had been working on this for a while. Reckon it'd be a win for fish, divers and the HKIA scrap aircraft parking department.
