If MH370 crashed in southern Indian Ocean it wouldn't be seen or heard (average depth 11,000 feet)

The southern Indian Ocean, where investigators suspect missing Malaysia Airlines Flight MH370 may have come down, is one place where a commercial airliner can crash without a ship spotting it, a radar plotting it or even a satellite picking it up.

The empty expanse of water is one of the most remote places in the world and also one of the deepest, posing potentially enormous challenges for the international search effort focusing on the area, one of several possible crash sites.

“In most of Western Australia and almost all of the Indian Ocean, there is almost no radar coverage,” an Australian civil aviation authority source said, requesting anonymity as he was not authorised to speak on the record.

The Indian Ocean, the world’s third largest, has an average depth of about 3600 metres. That is deeper than the Atlantic where it took two years to find wreckage from an Air France plane that vanished in 2009 even though floating debris quickly pointed to the crash site.

1. It's probably been hiding in plain sight all along.

2. into the abyss

if you watched the show 'Draining the Oceans', you know what we call islands are the tippy tops of undersea mountains




Grand Bahama Bank, which rises more than 2 miles high from the Atlantic abyssal plain.
The Bahamas Islands are but the tips of these massive structures

3. Aircraft engineers insist that much of the interior is bouyant.

Not to mention the luggage.

Stuff will float and wash up ashore.

4. Aircraft engineers are ignorant of the Old Ones.

6. That's what I was thinking.

If it ditched into the ocean, then eventually something will wash ashore somewhere.

7. I'm guessing (in a wholly amateur and uninformed way, of course) that it was

pilot suicide - and that the aircraft was set down as gently as possible in a very remote part of the ocean after everyone on board had been killed/incapacitated by decompression. If the plane was ditched carefully to remain somewhat intact, the floating wreckage may have been minimized...
