Shy The Wessex that ditched in HK was XR 500 IIRC - no fatalities and would have been about mid-80s. Will look it up.
One understands the pilot concerned subsequently "did time" for some sort of insurance scam (??) but I may be getting confused ......
[Edited to add:
A few years out! Got the right frame (XR 500), but it was April '79
