I believe the hulk of the 402 was found some years later when a former TAL/Pixie/ pilot(DM) got the salvage rights to the TriLander that went ker..splash in the same fashion.
I also seem to recall the diver on the job was a kiwi TAL pilot originally from Auckland?
Hope you find out what happened to Mike Sharpie.
He was one of the funniest buggers I ever came across.
Once while on a big search for a lost Baron at Nomad River in absolutely super ****e on the deck western district weather he piped up in his regimental pommy accent....
