Could the Chinese report be a
PR stunt (again)? I am by no means an expert and I guess this will be honored by being deleted from the mods - but detecting a plane everyone is looking for since a month with a rubber dingy, what seems a hydrophone on a pole and - seriously - iPod earphones? Apart from noise interferences from the dingy's motor (and it might be not in that frequency, no idea) but I would expect you want to wear a serious pair of over the ear headphones.
Regarding the two locations - possibly Voice and Data recorder at different locations (or sound carried from one to the other location but given the distance rather unlikely) - anyone daring to make an educated guess to the implication of such a find?
