Hello again cynwoody. Please read post 47 carefully. The 777 system is designed to work with the low earth orbit Iridium satellite system (60+ satellites). Since we know that the Iridium folks recieved 5 or 6 pings they should be able to produce a ground track. The 2 circular tracks you see on TV must have been obtained accidently by a geo comm sat picking up one of the pings. Another sat would still be needed to triangulate. The big question is why haven’t the Iridium folks come forward. Maybe they have and that is where the destroyer Kidd went.
The plane is at the bottom of the ocean and it may or may not be eventually located.
