re: the satellite "pings" (like a telephone searching for a cell tower)
It seems to me that this is something that
whoever did this, did not think about or did not know about.
They obviously wanted the plane to be un-traceable, which is why they turned off transponder and the other ACARS thing.
However, the plane was still semi-traceable due to these pings.
IF whoever did this, knew about the satelittle pings, wouldn't they be afraid that either Malaysia or China would get this ping information EARLY on, as soon as they discovered the flight missing on the radar, and tracked down the plane. (If they had gotten info. early, they would only be a few hours behind the plane).
IDK, it just seems to me like whoever did this did not know about this satellite ping thing.
