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

it happen than IF it would happen.







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

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?



Yeah, I wasn't saying anything different from any of this. Only that if

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

our lifetimes.



Just a few years ago they did exactly that. They recovered the Air France
black boxes in a similarly deep ocean without benefit of the pings. It
took 2 years, but they did it.
