4TB? Are you sure that's a crazy number. Even 4GB would be a lot of data.
Yes, quite sure.

A lot is streaming data that isn't stored, but 1tb/engine is easily possible for useful data retention.

Google about what GE are doing with their Predix platform.

noticed this article as well.

seems to point to a burn out situation not controlled landing.

Cost has been mentioned before ... but it's surely occurring to all of us that the cost of sending the data for all flights would be less than the cost of searching for the rare ones which get lost?
Given how many flights there are, I'd imagine that this isn't the case at all. Even in the last 10 years, there are very, very few planes that just disappear.
Correct. Plus the airlines themselves have to pay for all the data and they run on tiny margins. If aircraft go missing it's the manufacturer and the states involved that pay for the searches etc.

Producing huge amounts of data is fine and valuable. Transmitting it, live, from an aircraft in flight is rather more difficult.

In the MH370 context a fairly small subset of that data would suffice.

And it has to be somehow be unable to be switched off, which is the problem with finding this aircraft in the first place.

The mystery with this event is that the pilots(s) switched of the acars. That's a pretty rare and unusual set of circumstances. Is it really worth mandating against this kind of thing? Just in case someone else decides to make large aircraft disappear? It's never happened before.

I know. Sorry, my reply should have been more clearly posted as off topic, as it is connected but largely irrelevant to the topic.

I don't think it was off topic. Real time monitoring was in place, but ineffective. Illustrating just how much could be was informative.

It was partly off topic - as the larger data sets are always intended for batch upload rather than real time (at least for now)

Zahid Raza, the Malaysian diplomat investigating MH370, has been assassinated while in Madagascar. His car came under gunfire as it was being driven through Antananarivo on August 24th.

"no find, no fee" could be a risky venture. I suppose it'll come down to what they class as found.

It still looks very odd.

The pilot practiced broadly similar Pacific flight patterns at home in the months before the event.

The plane clearly hit the water hard and smashed into hundreds of pieces.

At least 10 pieces of the plane have been found so far, with another 5-10 pieces found probably also from the plane. They were mostly found off East Africa.

So, the London satellite pings and Pacific ocean currents should give a fairly good idea of where it went down. But the searchers seem as far away as ever.

It's all a bit odd, in this age of on-Earth, on-sea and in-space tracking technology.

it's true they give a good idea but chief searchers can't go over their ego to change the basic premise which failed badly (as expected)

might also be hard to confess you made wrong assumptions when it costed taxpayers >$100M
