thank you so much, elizabeth. that debris field is sinking further and could be moved by the current. could have moved dozens of miles from its original location. we don t know what the original location is at this point. right. when you have these large chunks by satellite, by the time they get there, they could, as you point out, be sunk to the ocean. we ll have michael kay coming up talking about what the search patterns are. we have new information about the final hour in that cockpit based on a new transcript on what was said back and forth to flight control. we ll read through about the altitude, climbing, and then a second part of this. here s the first part as the aircraft was radioing back. here mh-370 saying this is mh-370 please climb to altitude 250. going back and forth saying this is our flight we re climbing altitude 250. they continue to climb to 350 and on and on and on.
