I've tried MANY times, from multiple computers. This could correspond to approximately the very last hour MH370 could have been flying. Does anybody know anything about this? Can anyone else watch that hour?
Besides, the signal first fell off the flightradar map on 07/03 at 17.20 which would make the potential last few hours of the flight be up to around 1am on the 8th.

Each air frame is assign a 24 bit ICAO code that stays with the frame for the life of the craft. Every Mode S and ADS-B packet includes this code which uniquely identifies to (purported) originating frame. On the ground databases may be used to map this ICAO code to a current civil registration. This code is set into the transponder during manufacture or certain maintenance procedures. It is not accessible to the flight crew.
In certain Mode S and ADS-B packets their is a 'Aircraft ID' field. This can be set by the flight crew. The value of this field is usually set to the flight code (e.g. MS318) or the civil registration otherwise. If this is changed in flight it might cause some real time confusion but cannot cause problems for any post event analysis which will go back to the ICAO code.

Latest update from Aviation Herald.
"On Mar 16th 2014 Malaysia's Minister of Transport said, that the search has become much more difficult now including 25 instead of so far 14 countries including diplomatic efforts. Areas of land in 11 countries are being searched. Satellite data, primary and secondary radar data as well as search aircraft and ships are being requested. The aircraft took off with the fuel planned according to flight plan, there was no additional fuel loaded. The investigation refocussed on crew, all passengers as well as all ground personnel handling the aircraft. The crew homes have been searched, the captain's flight simulator equipment was dismantled and re-assembled at police premises for further investigation. The crew members had not requested to fly together. The team of Inmarsat have arrived in Malaysia supporting the investigation. Priority is still on the search and rescue operation. There have been no attempts to contact Malaysia, the airline or any other party in order to seek ransom or other compensation in exchange for occupants or the aircraft. There was no hazardous cargo on board, the cargo has been checked according to standard operating procedures. The satellite signals could also have been sent while the aircraft was on the ground as long as there was electrical power available."

So this surveillance airplane circling above "Al Qaeda territory" is sending out messages like
Now I'm here, no, now I'm here, no no I'm here now Shoot me, oops I'm here now shoot me SHOOT me
I just can't believe that a military airplane would use ads-b and continuously send out it's own position.
The more I read about all this, the more I'm baffled
We live in huge secured world with even huger security loopholes...
Now, if you look at the GLEX (Sentinel) track history you'll notice that it doesn't enable its transponder until reaching operating altitude, and disables it before landing. A safety precaution to avoid being targeted by hostile SAMs (surface-to-air missiles). As FR24 shows, the Sentinel cruises at FL420, well above commercial airliners and quite out of range from any Taliban-controlled missile platform (e.g. MANPADS), which commonly have a flight ceiling of some 15k feet (4.5 km).

A question - is it possible for a passenger (or passengers) to use an electrical device to take over the aircraft or to assist them disabling the aircraft ACARS, transponder, or computers etc? Remember there were at least 20 persons on board from an electronic specialist company.
Another question - when you pass through airport security and your hand luggage is x-rayd are the images recorded and possibly kept (if yes for how long?). If so might be worth going through this data. I appreciate if covers a lot flights and not just MH370 but might be helpful.

We know that Captain Shah posted web videos, so there are samples of his voice. However it's not clear if there are any good voice samples of the first officer. Ditto for the cabin crew and passengers.
Even if someone attempted to compare "voice prints" to the radio transmission, the fidelity of the recording isn't likely to be adequate enough to produce conclusive results. The last transmission was made at the limit of the range of Malaysia's air traffic control system, and amplitude modulated signals get covered up with noise as distance increases.
Perhaps the US has some secret technology that might clean it up enough to get something, but that will take time and the cooperation of the Malaysian government. So far there's no word of what the NTSB inspectors sent by the US are being granted access to, if anything.

Looks like another development - Malaysia is asking for permission to investigate countries that are not under government power - as its a possibility that its gone somewhere Taliban has power over such as near the afghan boarder between Pakistan and Afghanistan, but that still brings the whole radar question why was no one questioning the flight going over all these countries?

It is possible that someone on board the flight who is an aircraft service technician (or knows one) could carry on service equipment (most likely a laptop) that could interface with the plane's internal computer network, and with the right passwords (the 777 uses the UNIX operating system) log in and change settings. This would require the cooperation (voluntary or coerced) of the flight crew of course. Nobody could take control of the plane while sitting back in the passenger compartment.
Another question - when you pass through airport security and your hand luggage is x-rayd are the images recorded and possibly kept (if yes for how long?).
Is there something in particular that you think they should be looking for?

As for "the whole radar question", I strongly doubt that nobody was watching the RADAR in the entire region during the flight. It's far more likely that no other nations are reporting anything because there's nothing to report.
I'll bet that every aviation authority within range of the missing flight is going over their RADAR tapes right now, looking to see if they can find any trace of the missing plane. But after the way that the governments of Malaysia and China have mishandled publicity of this incident, I'd also bet that they're not going to say anything unless and until they're absolutely certain that it's meaningful. It's entirely possible that the missing plane sneaked into another nation's airspace unnoticed by acting like a GA plane, flying slow and low. And perhaps there's a tape somewhere showing an abnormally large primary return for a GA plane. Just don't expect anyone to come forward without first double and triple checking it first.
