Apologies if this has already been mentioned, but why don't black boxes transmit their information directly to a computer or a satellite? It seems mad with the technology that we have now to be physically looking for something in the sea

The air France report suggested all black boxes had 90 days of battery life. I think this will be implemented by 2018 or something...

Ppen, I think because of the expense, and that would be a vast amount of data being stored. The black box isn't really a locator device, it's a recording device, the other systems (which Malaysian didn't subscribe to) give more location information .

Remember the Mail ran an interview with the Captain's daughter indicating he was lost and suicidal before the crash?

Well it appears that it was totally made up

That is surprising

Back in the eighties friends of my parents were moving back from the middle east and put all their house contents on a shipping container which fell off - they lost all of their carefully packed possessions bar the suitcase of clothes they had travelled with. I am not sure of the details but they were informed about it and I believe they were compensated by some sort of insurance - but were still devastated. To top it all, their perfectly healthy dog was "mistakenly" put down whilst in 6 month quarantine.

Pauline, I'm really not sure there's a signal that could make it through a 2-mile density of water intact, then travel through the air to a satellite station!

Dear me, Forago, that must have been upsetting! Almost worse than losing everything in a fire.

Forago that is awful :(
I cannot get over the fact things just 'fall off' ships!

They don't just fall off - the floatees above were washed off in a storm - one hell of a storm to dislodge a forty foot container, I get scared watching the boat scene in Wolf if Wall Street!!

That scene was scary though Doctrine!

Garlic No, that's very true when you think of it in those terms. Two miles of water is a hell of a depth.

PaulinesPen - to be able to transmit through 2 mile depth of water and then the hundreds of miles to a satellite would require a large antenna and a huge battery to be able to drive it for 30/90 days. This would increase the size of the black box considerably and as the black box becomes larger the less likely it is to survive a plane crash.

It's about compromises. It's better to have a black box that is likely to survive more than 95% of crashes rather than one that, in theory, is able to broadcast from the bottom of the ocean but probably won't survive a crash.

Not to mention the pressure at a depth of two miles

I still stick to what I said on 26/3/2014.

This thread didn't start till after that do unless you are going to tell us what that is it's going to remain a mystery. I certainly can't be arsed to go back and find it.

!

I think she said she doesn't believe a word of it. I'm just guessing.

Did anyone see the CNN interview with Sarah Bacj, girlfriend of Philip Wood, by any chance? I can't find it online

Oh, found it here

BBC breaking news says a Chinese ship has picked up a 'pulse' but they don't yet know the origin of it!

Please let this be it!

Just saw the breaking news, please don't let this be a false alarm again!

Anyone have any idea what else could be down there sending out a pulse signal? Surely if they've found something sending out the right sort of signal in what they think is the right sort of area then it's incredibly unlikely to be anything else! I guess they can't say for sure until they've actually got hold of it though, just in case!

Fingers crossed this isn't a false alarm

Fingers crossed it is not a false alarm!!
