RE ACARS- PINGS- TRACKING
FROM WSJ . . ." The automatic pings, or attempts to link up with satellites operated by Inmarsat PLC, occurred a number of times after Flight 370's last verified position, the people briefed on the situation said, indicating that at least through those five hours, the Boeing Co. BA -2.04% 777 carrying 239 people remained intact and hadn't been destroyed in a crash, act of sabotage or explosion.
Malaysia Airlines said it hadn't received any such data. According to Boeing, the plane's manufacturer, the airline didn't purchase a package through Boeing to monitor its airplanes' data through the satellite system."
IMO- there is a lot of confusion re pings and data by most of the media
depending on whom you believe
1) MA did not buy the online- enroute maint package- therefore pings may only had or RR only received takeoff and climb and mayberf level off data- thus the " no data " after xxx comment
2) The simple pings may only contain altitude and speed data- triangulation by sigint or other satellites may reveal course
3) The difference in time between Acars data and turnoff of transponder may be simply due to ACARS time intervals re pinging
4) Its doubtful the Pentagon would re route a destroyer/ship AND P8 without a bit more positive info than reported
5) actions re shutoff of systems seem to be deliberate- rule out explosion
6) IF deliberate - why not fly to deepwater and dive in - no claims by any group will have greater longterm effect ( re cost $$$$$ and unknown FUD ) than simply saying ' we did it "
7) On a $$$ cost basis, the 911 was very effective and made a major change in air travel and security costs
8 ) almost any-every indication and analysis seem to indicate a deliberate action by ?????
(9) AD re corossion is a non starter as is my post about future tie in of FBW and entertainment systems PLANNED BUT NOT YET IMPLEMENTED-
JUST MHO- FWIW
