It is a media circus. Between the Inmarsat and Tomnod data, it appears that the plane slipped away to a location northwest of Australia. Perhaps the
MH370 hijack went bad and the perpetrators gave themselves hypoxia.
If the plane had been on HFDL, some listeners might have gotten some data bursts. This one was more high tech and linking via satellite.
May the pax and crew rest in peace.
