>>They represent an approximate maximum distance from the receiver, but absolutely nothing else.<<
No, you are misunderstanding the meaning of those arcs. They indicate that, at 8.11, the plane was located on the arcs somewhere, but that’s it. It has nothing to do with “maximum distance from the receiver” and everything to do with “approximate distance from the satellite.” In other words, it’s not a maximum distance, it’s a more or less exact distance from the satellite (or receiver as you call it). And it would be very difficult to land the plane in Pakistan before 9.11 from that distance, even assuming it were anywhere near the northern part of the upper arc at the time.
In fact, the searchers seem to have enough information to be concentrating on the southern arc in the Indian Ocean instead.
You simply do not even understand the problem.
No place on this thread to educate you.
The plane most certainly did not travel along either of those arcs.
