What surprises me about path reconstructed from immersat: the angle to the satellite is always the same, but the pilot didn't know (or care) the position of the satellite. So there is no reason to follow such a path (a straight path would change the angle) . This seems like a too big coincidence. To me the only explanation (except a huge coincidence) is either a stationary plane or of course faulty data.
