Why MH370 drifted underwater to Africa:

How come it never occurred to all the clever expert MH370 investigators that MH370 only sank partially in the deep Indian ocean and it drifted, pushed by ocean currents all the way to Africa?

Nuclear attack submarines sail secretly to a location in the ocean where they switch off engines for months to avoid detection. They do not sink or float to the surface because they adjust the air and water in ballast tanks such that they remain at the same depth through the months they are in station.

JUST AS NUCLEAR SUBMARINES CAN PASSIVELY REMAIN AT A CERTAIN DEPTH WITHOUT SINKING BY ADJUSTING AIR IN BALLAST TANKS, IF MH370 LANDED INTACT IN THE OCEAN IT WILL ONLY SINK PARTIALLY TO A CERTAIN DEPTH AND THEN DRIFT TO AFRICA PUSHED BY CURRENTS.
