it sunk in the process of transferring it to Hamilton island
What! The recovery vessel sank?
No! You don't mean after they beached it on Dent, they decided to drag it across the channel to Hamiltion Island, then lost it?
According to an unreliable source....
Boats attempted to tow the aircraft back to Dent Island but failed and it sunk shortly after the crash.
A bit too much poetic license being used here to describe events!
Otherwise known as good old aussie exaggeration!
