I managed to access it and tried to make a couple of screen shots, here is a zoom:

And the normal view is here
Unfortunetly this looks more like 2 boats to me...
(Other than that, Tomnod is working a lot better here tonight, I am using Chrome and it is fluid, not like yesterday where it was taking minutes to load a square)

The 777 is an aircraft with an enviable record. Of the three hull losses in its approximately 20 years of flying, only one is possibly attributable to Boeing (MS 667). BA 38 was a problem with the engines (RR Trent 800 series) and OZ 214 was pilot error.

TDB is wrong -- As I mentioned earlier, there are at least three scenarios in which the crew could have been incapacitated and the plane could have maintained level flight for a long time.
Read the Wikipedia entry about Helios Airways Flight 522. Ground crews set that plane's pressurization system to "manual" in order check for a leak, then forgot to reset the system to "auto". The plane took off, a lack of oxygen incapacitated the crew, and then the plane flew on autopilot until it ran out of fuel.

+1. Everyone just wants instant answers or anything for that matter. Everyone just needs to chill out. We won't know anything conclusive for a while.
I've seen firsthand during natural disasters where reporters are desperate for a news piece and would be seen interviewing some low ranking police officer. It then would be published as a local "official" being quoted with saying <insert information/clue here>. That story would then be picked up by major news outlet which would lead people to believe that it's fact.

That being said, some blame can also be attributed to Malaysian authorities. They didn't organize their release of information or public relations very well. Some of this may be understandable given their lack of experience dealing with the scale of such an air disaster. However, it also does not excuse some of their poor management and delays releasing information either.

777 "Black" Box question
How much data can the "black" Boxes on the 777-200 store?
If the plane flew for 5 - 7 hours after the transponder went dark, would the data from the incident be overwritten?

China search broadened to land areas
China now appear to be expanding the search zone to include land areas as well, according to Reuters. This is the first time the scope of the search has officially included land masses.
China’s air force will add two planes to the search for a missing Malaysia Airlines jetliner, the country’s civil aviation chief said on Wednesday, adding that search and rescue efforts would be broadened to include land areas.
Li Jiaxiang, chairman of the Civil Aviation Adiministration of China, made the comments on the sidelines of China’s annual parliament.
In one of the most baffling mysteries in recent aviation history, a massive search operation has so far found no trace of the aircraft days after it disappeared carrying 239 passengers and crew. (Reporting by Shen Yan and Michael Martina)

On the other hand if the black box can record 10-12 hours of data at a time before being written over it's irrelevant.
I don't know the answer to that question - I remember always hearing that the cockpit data recorder only recorded the last 30 minutes of audio but don't know if that's changed.

The flight data recorder stores a minimum of 25 hours of information; the cockpit voice recorder stores a minimum of 2 hours of information.

I don't think thats the question. I think it's more how much data is the black box recording. That is - say it flew for another 5 hours, if the black box only records the last 30 - 60 minutes of data then we may not get any relevant data from the black box since the last 30-60 minutes would be the actual crash and not the event that caused it.
On the other hand if the black box can record 10-12 hours of data at a time before being written over it's irrelevant.

If you are talking about the Flight Data Recorder, it should be able to record the whole flight (it is mandated by law to record up to 25 hours of data). Even if the transponder is off, there is a whole range of parameters that the FDR monitors:
http://www.airlines.org/Pages/Flight...Recorders.aspx
Regulation amendments have mandated more capable recorders as technology has made them available. Initially, the Federal Aviation Administration (FAA) required that airplanes designed and "type certificated" prior to September 30, 1969, record six flight parameters: altitude; airspeed; heading; vertical acceleration; time of day; and the relative time of radio transmissions to and from air traffic controllers. Airplanes certificated after that date were required to record a total of 11 parameters, adding to the list: pitch attitude, roll attitude, longitudinal acceleration, control-column position, and engine thrust indications.
The FAA subsequently required that, after May 25, 1989, turbine-powered commercial airplanes have DFDRs capable of recording 25 hours of data. Those certificated after September 30, 1969, or manufactured after May 26, 1989, had to record 17 parameters on any flight after May 25, 1994. The six additional parameters included: pitch trim position; control wheel position; rudder pedal position; position of each thrust reverser; trailing-edge flap position; and leading-edge flap position. FAA also increased to 29 the number of parameters required in airplanes having diigital data systems, or manufactured after October 11, 1991.
Current Regulations for Flight Data Recorders
On July 17, 1997, FAA adopted the regulations to again increase the minimum number of parameters that FDRs must record. Under this "97 rule," airlines were required to modify, by August 20, 2001, airplanes manufactured before October 12, 1991, to digitally record either 18 or 22 parameters, depending on whether or not the plane was equipped with a flight data acquisition unit. By the same deadline, airlines modified newer airplanes to record 34 parameters. Airplane manufacturers modified airplanes manufactured after August 18, 2000, to record 57 parameters, and airplanes made after August 19, 2002, must record 88 parameters. These parameters are derived from scores of sensors imbedded throughout the airplane - more than 1,100 sensors are needed in some models to collect 88 parameters. Collectively, this array of sensors reads not only the status of key data items, such as altitude, but documents the overall performance of systems, including: engines; navigational aids; warning systems; hydraulic systems; electrical systems; and flight controls. Current FDRs must retain the most recent 25 hours of flight data. FAA estimated that the modifications of airplanes already in service, as required by the provisions of the "97 rule," cost the industry $309 million.
Current Capabilities of Flight Data Recorders
The net effect of the periodic upgrading of FDR regulations is that, depending on the age of the airplane, US commercial airliners currently record a minimum of 18, 22, 34, 57, or 88 data parameters. As older airplanes are retired, the lesser minimums will, in effect, expire.
