A 772 Driver has confirmed that it would not be physically possible to get up to FL450 with a full load and 7 hours fuel minimum on board. In fact, I would be very surprised if it could even get to 400? 772 Drivers please advise.
It's not clear where those altitude data came from, especially now we know that the Satellite was NOT receiving such data?
The altitude excursion data was attributed to leaked Malaysian PSR returns on the unidentified target (presumed MH370) at IGARI sometime shortly after transponder switched off.
