Malaysia has declared an end to the search and officially attributed the loss to an accident. So it looks as if we will never know what happened. Hopefully, real-time transmission of flight and cockpit voice data will be ushered in by this, so that this data isn't dependent in future on finding two orange containers at the bottom of an ocean.

I doubt the bandwidth exists to do this - the continuous data flow from appx 100k commercial flights per day would surely far exceed satellite capacity (many flights spend hours outside of vhf range - hf has very limited capacity and is no good for reliable real-time data transmission).

Many airlines subscribe to services that send performance & fault data anyway. Often to their engineering depts. and to others such as engine manufacturers. They use satellite links, usually. These days, many airlines also provide internet access and phone services for their PAX. Flight parameters and cockpit voice data aren't going to be especially bandwidth intensive.

 

Here is the US NTSB's recent letter on the subject. They are proposing a burst of recorded data triggered by a set of abnormal conditions.

The search is not over.

Ah - no, you are right. The BBC breaking news item that my link originally linked to stated that the search had been ended.

There are currently four vessels searching the southern end of the "seventh arc" where it is thought the plane went down.

 

The ATSB releases a fortnightly bulletin here http://www.atsb.gov.au/mh370.aspx

It's a BIG ocean...

The BBC are reporting that it is almost certainly from a B777, and that it is being taken to Toulouse for examination by the BEA. I should think the odds are very high that if the wreckage is indeed from a B777, it is from MH370. It's the only one to have gone into the sea.
