Also, the plane should have veered to the East, not the West.
EDIT To clarify for the downvoters: I was hoping so because it is the only chance all those people could still be alive. Which sadly they aren't.
You're (as alot of other people) are grossly underestimating the problem of tracking things across oceans.
Not to mention the other simple fact: what's the point? Is there a difference if plane is found 1 day or 14 days after crash? Reliable tracking would be a huge investment into a system that at the end, wouldn't make much difference in survivability or cause of accidents.
If you're a relative of someone who was on board, yes, yes there is.
Two variables here: 1) ADS-B Transmissions are line of sight, so once you are far enough off shore there are no ground stations to receive the data 2) Ground stations are provided by volunteers, so there isn't a critical mass of volunteers that provides 100% coverage over even ground locations
