Just reported on UK BBC News, Inmarsat apparently gone public with the view that:
(a) they are surprised that the search continued in the S China Sea after last Wednesday, 8 days ago, when they sent the satellite data to Malaysia, as the pings clearly pointed to the two well-known arcs we've seen as the likely location of MAS370
(b) they can't understand why the concentration on two corridors following the two arcs because in their view the aircraft was at one end or the other, not somewhere along the arc, "according to the laws of physics", and most likely to be south as the northern route would have likely been picked up by radar as it crossed several countries.
Up until this point I'd been willing to give the search management the benefit of the doubt but this latest fiasco is pretty much proof that they're muppets.
One question I had was on knowing the turn was entered in the FMC.... was this deduced because the next waypoint was seen in ADS data received before shutdown? Has anything specific (lat/long) been divulged?
