Thanks. That's about what I'd expect. So, if Inmarsat's analysis is correct, we don't have to wonder if the plane might be in another location due to a changed transponder hex code?

Of course they have. Because, again, having the ability to take control of a plane, and crash it wherever you want to makes PERFECT sense. And apparently everyone on Diego Garcia is blind too, because no one has seen it there.
This article points out that based on the ping data the aircraft would seem to have been programmed to the south instead of flying on autopilot after last way point.
Now for an interesting piece of information that does not appear to have been considered in detail. A pilot on PPRUNE pointed out that there are two different modes of operation of the 777 flight management computer. A programmed route will take a straight line (great circle) route to the next programmed waypoint, but if there is no longer any waypoint in the computer, then the plane will fly on a magnetic bearing. While this is not material around Malaysia, it becomes highly significant in the Southern Ocean.
As a result, a magnetic heading would need to start out going significantly further west (and would also fly much further) to end up at the same point as a great circle route.
It is easy to see that in combination with Jeff Wise’s chart of the ping lines, a magnetic bearing heading is highly unlikely to have resulted in the 3.11am ping arc lying outside the 2.11am ping arc. Once this is realized, the hypothesis that the plane suffered an accident that left it flying on autopilot becomes rather less likely than the plane being deliberately directed towards a part of the southern ocean where presumably whoever was in charge believed the aircraft would never be found.
Indeed the NTSB tracks appear to implicitly assume an absolute not a magnetic heading, so would require the plane to be flying in a pre-programmed direction. Of course we need to see the ping arcs themselves (or at least get absolute confirmation about the trend in the ping arcs) before reaching a definitive conclusion, but this issue appears quite significant for any assessment of what might have happened onboard MH370.

and of course having followed procedures,,,,,
too the pilots horrow,, the flight control system was indeed hijacked,, and the earlier,threat was implimented by the flight computer software,, assend to 45,000 ft,,
ps do not attempt too dissengage,
have a nice day
You cannot remotely hack the onboard systems. You would have to be present in the plane and hooked up physically to the system. It's not like the computer is hooked up to the internet....
The most secure computer is one that is not powered up and is locked up in a closet.
The second most secure computer is one that is not networked....the only way to hack it is to be physically present at the keyboard.
You cannot remotely hack the onboard systems.

Yeah, I get it, that's what you believe, I already knew that, however....
This old boy remains open to the possibility there are other ways to track aircraft than that over the horizon thingamajiggy.
It remains my opinion that Diego Garcia is armed to the teeth. To convince me the Navy is unaware of stray aircraft flying by to the east, west, or otherwise would take quite an argument.

So how does Radar work on a Submarine???
Or do they use something similar to Radar???
Not to sound argumentative or pedantic, I'm genuinely curious pal!!!
I'd also say my point was in terms of "
forbiddenclassified ATS technology", which probably finds a loophole in our knowledge of the Laws of Physics, compared to the SS of the Superpowers!!!
Edit: I thinks it's SONAR as the person above has said, could be wrong again though!!!
