[amsat-bb] Malaysian airliner puzzle

[Anthony Japha]

Those so-called arcs that are said to be possible routes for the plane look much like the outer edge of one of the Inmarsat footprints.  Is there logic behind the arcs or is it oversimplified nonsense?  They are said to be the result of the signals Inmarsat received.  But then why wouldn’t it be possible for the plane to be anywhere in the footprint?

I’m sure many in our group have good ideas.  I’m not trying to start a discussion of the entire mystery, only this one narrow, but possibly misleading, aspect related to our hobby.
