UPDATE [12:37]: Tuoi Tre, a leading daily in Vietnam, reports that the Vietnamese Navy has confirmed the plane crashed into the ocean. According to Navy Admiral Ngo Van Phat, Commander of the Region 5, military radar recorded that the plane crashed into the sea at a location 153 miles South of Phu Quoc island.
When contacted, Malaysia Airlines declined to confirm or deny the reports, saying that the Malaysian authorities are working together with the Vietnamese government on the matter.
Meanwhile, Al Jazeera reports that China has dispatched two maritime rescue ships to help locate the missing plane.

Thanks so much for the expertise of so many freepers and the discussion of what might have cause the crash.
Much better reporting then the MSM
So true. How horrible for the parents of infants to know what is going to happen. God Bless them, may they Rest In Peace.
Question for anyone who would know:
Why isn’t all the info recorded in the black box of an aircraft(location, communications, data readouts, etc), immediately uploaded to some online service(Cloud?) in real-time?
I understand the continued necessity of the black box as a signal-beacon should something go wrong and the plane needs to be found, but doesn’t the technology exist to transmit all flight data in real-time?
You forgot Arator LOL.
They wait a while to be sure contact has actually been lost and the pilots aren’t just having comm problems, before they officially say the plane is missing.
FR24 data indicates about 40 minutes or so in the air.
“Why isn’t all the info recorded in the black box of an aircraft(location, communications, data readouts, etc), immediately uploaded to some online service(Cloud?) in real-time?”
Qualcomm has been working on a real-time data system via satellite that they patented last year.
It’s still a few years off, but it has all kinds of implications for aircraft operations management.
From all the commercial airliners in the air?
That’s a lot of data.
What’s needed is a burst transmission in the event of a parameter going out of normal range, like cabin pressure, or a sudden high G reading, or an engine failure, etc.
That way the data is only transmitted from the plane that is in trouble.
They are working on such.
There are also ejectable recorders, and ejectable crash position indicators, designed to eject from the airplane and thus survive.
It sounds like there was no radio contact reporting a problem. So whatever happened happened fast and required the crews full attention all the way to the end. That’s the only speculation I’ll offer...
BA038 had a third recorder, a QAR, that could be accessed remotely through a cellular link if necessary.

“From all the commercial airliners in the air?”
Yep...
Operations will have real-time parameters on every flight, and anything non-normal will immediately trigger an alarm for the dispatcher.
The real problem is satellite access, it will probably require dedicated birds.
This has real implications for large airlines, with the potential to save billions of dollars a year in costs (fuel, engine wear, etc.).
The pilots won’t like the company “looking over their shoulder” though, just like cockpit cameras. Count on it.
ACARS probably satifies the need already. It was very helpful with AF447.
“This flight did originate out of a country with the largest population of Muslims in the world.”
No it didn’t.
Another Tweet:
Search and rescue operations have covered a 40 nautical miles radius, says Malaysian Maritime. No signs of MH370 yet
This goes way beyond ACARS, transmitting real-time data such as engine revs, fuel feeds, cabin pressure, flap settings, control inputs, etc. Something like 100 parameters, or more, that can be monitored in real time at Operations.
It’s a lot of data, but isn’t particularly storage intensive. Assuming all the readout data is kept digitally you’re talking about a very small amount of storage space required. The most storage space would come from any recorded audio. And I’m sure they could have a system to prioritize any audio that should be recorded/shared.
Your burst transmission system seems like a good idea too, but only if you had a reliably dedicated uplink at all times.
Either way, just wondered why the tech isn’t universal yet. I figure if all the passengers can watch youtube movies in the back of the plane, it should be a relatively simple task to send the plane’s inflight data out.
United States of America - 3 plus 1 infant were on that plane.
Yes, it’s been discussed often, and was really pushed after AF447.
I doubt we see it any time soon, as crashes are so rare. It’s not seen as necessary yet.
“Could this be the needed ‘diversion’ to shift people’s eyes away from Obama’s cratering, ongoing failure in the Ukrainian Conflict? I expect that group to cook up something strong, to force a shirt in news focus for a week or two”
Seems it’s the wrong airline and Nationality of the dead for much of that to happen.
About the most sensible contribution on this thread so far.
