I'm pretty sure they will find the plane. It may be a year or two but they will find it.
I am surprised nothing had washed up on shore somewhere.

Yep, ever read books about submarine warfare. How different temperature or salt layers can hide a sub from even active sonar. In WWII subs were only good for 300' or so and the technique worked well. This airplane could be in 14,000' of water.

Yes but one would think that a beacon that is designed to be located underwater would be able to be located underwater. Does anybody know the approximate maximum range of the ULB? A few weeks ago I saw numbers like ~1000 meters on Pprune and A.net meaning that you would have to be almost right on top of it to pick it up, but now it seems like detecting this possible beacon still leaves thousands of square miles to search?

I am not to familiar with under water diving and such, but kind of equipment could go down to 14,000ft if the 777 happens to be down there? I would think there is only a few vessels that can dive that deep, if any. Even if they detect it to be down there, it seems like an immense challenge to get even a submarine or people to see it let alone rescue anything from it.

How much pressure can a black box take?

Well...yes, it is. And using acoustic energy is the best way to do it in that hostile and varied an environment, unfortunately. If there was a better way to do it, I'm sure they'd go for it.
ROVs are likely the best bet - things that do not have air chambers or have very, very small ones are likely to be the only things that can get down that deep, unless they are specifically designed for immense crush depth like the bathyscaphes that have set some records. I imagine those have very limited utility, though, as they are designed to go up and down and not do much maneuvering or manipulating while down there.
That's a really interesting question. Depends on the design, of course. If it's a solid-state device (i.e. - no airspaces) and it's at least sealed off from corrosive seawater, then there's a really good chance the thing is intact. Things which are built densely are inherently crush-proof.
Here's an interesting bit for you. I read once that glass is actually a much better medium for building a submarine hull than steel, because it is much more resistant to crush-pressure given the density of being a supercooled liquid. It's mentioned in one of John Pena Craven's books - I'll try and dig up the reference later.

I would guess solid state but wondering if the box was compromised if in that depth due to pressure. Hopefully once found data can be recovered.killbilly said:
Anyone know if the AF boxes compromised? I know data was recovered but wondering. It was in 13,xxx feet.
Yes...Last week...It was right after the interview with the psychic and immediately before the ghost vs zombie plane discussion.

Here's a nice article that predates the MH loss. Much could be done to improve the range of ULB's by increasing gain and lowering the frequency.
Also, don't forget that the transmitter is only half the equation, your receiver is critical. There's a big difference between a passive sonobouy quietly doing its job at depth and a sensor towed behind a noisy ship.

This is the best news we've heard so far from a reliable source, including his expression of confidence. Hope he's right.
Angus Houston, head of a joint agency coordinating the search for the missing plane in the southern Indian Ocean, said that the Australian naval vessel Ocean Shield picked up the two signals on Tuesday, and that an analysis of two sounds detected on Saturday showed they were consistent with a plane's black boxes.
"I'm now optimistic that we will find the aircraft, or what is left of the aircraft, in the not-too-distant future. But we haven't found it yet, because this is a very challenging business," Houston said at a news conference in Perth, the hub for the search operation.

Find, or find not. There is no try.

About the only thing more difficult and riddled with both uncertainty and inaccuracy than sound triangulation is sound triangulation under water.

This is all the fault of global warming melting the ice making the airplane even deeper.

After all the crap over the last four weeks, I'm starting to become a believer. Heard the audible David Mearns of Blue Water Recoveries captured and it's hard not to have solid hope.

Co-pilot's phone signal detected after jet vanished.
Another possible clue into the plane's disappearance emerged Monday.
A U.S. official with firsthand knowledge of the investigation told CNN's Pamela Brown on Monday that a cell phone tower in Penang, Malaysia -- about 250 miles from where the flight disappeared -- detected the co-pilot's phone searching for service around the time the plane vanished.
The revelation follows reporting over the weekend in a Malaysian newspaper that co-pilot Fariq Abdul Hamid had tried to make a telephone call while the plane was in flight.
However, the U.S. official -- who cited information shared by Malaysian investigators -- said there was no evidence the co-pilot had tried to make a call.
The details do appear to reaffirm suggestions based on radar and satellite data that the plane turned around and was probably flying low enough to obtain a signal from a cell tower, the official said.
