There was an interesting discussion with Cousteau the son of the famous Jaques Cousteau and an expert in the suspect area.
Firstly millions of tons of waste are tipped into the Oceans.
second point he made is that the wreckage could be in 25000 feet of water.
The bottom is not flat but made up of mountains and valleys.
The currents are some of the strongest in the world not just horizontal but vertical currents.
After this length of time any floating parts could be hundreds of miles from the impact point!
It is exceptionally unlikely that there will ever be a definitive answer to this mystery and that this tragic event will be discussed for years with theories that it and its PAX are being held on some remote reef to a disturbed member of the crew doing something crazy.Probably even that some Galactic visitor took the aircraft away and its PAX for scientific study
With the huge insurance claims come vested interest??? probably that this was some sort of hijack of a serviceable aircraft to the aircraft faulty to the operator at fault.
So keep guessing guys as we will never get an answer
