It looks to be from something that was constructed using methods/materials to save weight.
IMHO, aircraft, TBC.
Can u advance on this assumption please i.e what in the video provides this evidence ?
Not really Richie as there is to be no more postings regarding the 2010 footage. The thesis I posted earlier on the Sikorsky S-38 aircraft after 60 years+ submerged in seawater and its subsequent recovery and restoration gives you some idea of what to look out for. It's not my thesis by the way
CORROSION OF ALUMINUM ALLOY 2024 BELONGING TO THE
1930s IN SEAWATER ENVIRONMENT, A Thesis by KEDAR GUJARATHI
"Wreckage of ‘Carnauba’, a 1930s vintage Sikorsky S-38 aircraft, a beloved icon
of SC Johnson's early history, was found on July 5, 2000, in seawater off of an
Indonesian island of West Irian Jaya"
I just posted it to show what to expect and, it is very thorough but hard work to read and absorb it all, very useful material though.
The photographs of parts of the wreckage are really excellent, take a look.
http://repository.tamu.edu/bitstream/handle/1969.1/ETD-TAMU-3002/GUJARATHI-THESIS.pdfIn the 2012 video footage of the wreckage from the Norwich City it was clearly seen that ship wreckage was still recognisable as such even after 80 odd years underwater, no mistaking that lump of steel and iron for anything else but ship wreckage. Where as the wreckage of the 1930's Sikorsky photographed in the thesis...well, judge for yourself but, it's hard to believe that it is actually parts from the 1930's Sikorsky S-38. So, if the smoking gun proof needed is a recognisable part with serial numbers and the like then images, photos and videos aren't going to provide it, they can only provide clues as to where to look.
IMHO of course
