Pprunners,
Lots of good ideas here, Thank You. I guess we'll never really know for sure, but I am leaning towards the Floating Gear Theory, as the pilot's report was quite specific but doesn't mention the gear, also a similar situation with the Dornier.
I can definitely recommend this dive!! It's quite deep though at 37m, so watch your Dive Computer carefully, to stay No Decompression!!!
Regards to All,
