on the immarsat they had provided coordinates to the researchers two days after the accident and where they are searching now. it also suggested more data from satellites and radar points to come. certainly more and more nations are providing information and assets to help in the search. of course you'd also want to wrap up back at home base, if you will, on the issue of what was in the pilot's information to close that door, that alleyway once and for all. what was in the maintenance records, anything outstanding. a lot of it is shutting down avenues so you don't have loose ends. hopefully additional coordinates coming in from other countries and from the satellite company will help them honey in. at this point if they don't get any wreckage, they have to theorize where the point of impact might have been based on few satellite handshakes or pins, where it would have run
