With RARE exceptions, debris that floats does not float for long.
Even the seat cushions that "are your floatation devices in the event of a water landing."
Don't believe me?
Go to your local marine supply and look at the life jacket labels - they say right on them how much buoyancy is lost per unit of time. Eventually, even the best life jacket you can buy - will sink.
Can't get to a marine supply? How about the US Coast Guard then -
~~~~~~Life jackets should be tested for wear and buoyancy at least once each year. Waterlogged, faded, or leaky jackets should be discarded.
Next:
In shallow relatively small, shallow seas with strong currents and tides, things that do stay afloat long enough don't ALWAYS stay out to sea - they wash to shore. Those that don't will wash out to the larger oceans. And then probably sink.
~~~~~~
Next:
This is not the Atlantic Seaboard of the USA.
Things that do wash ashore are not necessarily likely to be found by passing hikers.
Go to a developed, accessible beach area in any of several places in the South China Sea - I have - and after wondering and asking locals later why no one was down by the beach, expect to be met with: Why would you go there??

A great many of them are NOT clean and don't smell great, while others are simply not developed and are inaccessible due to the jungles.
~~~~~~
There are really fabulous reasons to understand that the further out in time we go, the lower the probability becomes of finding floating debris.
Hijackings, rogue military actions, conspiracies and space aliens need not apply for the job.
It's already taken by simple, cold, hard facts without any of that.
~~~~~~
Anything is possible.
~~~~~~
Including the most likely scenarios.
PS - if you've just seen the New Zealander/oil rig letter - it is not news and it did not just come out.
It may be news to you but that was posted on the internet and the guy was verified as a real person by New Zealand days ago.
No conspiracy required to explain why, "OMGZ, this is news!" like half the internet is saying.
By the way - don't be surprised when the news also discovers more OMGZ NEWS letters like that one.
KOTA BARU: The authorities here have their hands full after receiving at least two reports from the public that they saw an aircraft flying low on the same day Malaysian Airlines MH370 vanished.
In his report, the owner of a fishing boat claimed that he saw an airplane flying low while he was at sea with a friend about 14.4km from Kuala Besar in Pantai Cahaya Bulan here at 1.30am on Saturday.
Azid Ibrahim, 66, said the aircraft was heading towards international waters.
According to him, the plane was flying so low that he could see the lights
