At least with the Titanic, you had a much better fix of where it went

down and that was more a question of when the tech would develop to let

it happen than IF it would happen.



Yes, the rescue ships knew where it sank within a few miles.



If they don't find the ship before the beeper stops, they won't find it

in our lifetimes.



It's not very likely the pinging from the black boxes is going
to locate the airplane. It almost always works the other way
around. You find the wreckage, then you can find the black boxes.
The ping only travels a couple of miles underwater. The water
is a couple miles deep so a surface vessel or sub would have to
be very close to it to detect it. You can pull a hydrophone deep
in the sea, but again, given the huge area, there is no way
they are going to cover any significant amount of it using that
method in just a few weeks. How many vessels are at the site now
that are even capable of listening for the ping?



(Why not put longer-lived batteries in the beeper? I'm willing to

contribue two. )

A better system would probably be the streaming data type that
was very helpful in figuring out what happened to AirFrance A330.
Even if we just had the last GPS fix, it would probably be enough
in this case to find the black boxes.
