Re the possibility of JORN having tracked this flight--Intriguing possibility nonetheless considering the fact that the investigators do seem awfully confident of the resting spot--confidence that would seem suspect with ONLY Inmarsat's data as evidence. However I presume the black box pings have a lot to do with this confidence. On the other hand, it seems that they're reluctant to conclude that the black box pings are without a doubt from MH370.
I had another thought that I was hoping someone with technical expertise could answer. Could there be there any (technical/electrical/"____-"al) occurrences that would give off erroneous satellite pings? In other words, is there a situation in which the handshake signals to Inmarsat were completely wrong and not indicative of MH370's flight in the later hours (beyond where the track was known)?
