investigators have had a failure of imagination? in other words, are they not thinking of something because they re stuck on all these established theories? no, i don t think that s true. the way in which this investigation has evolved, you are now seeing major roles played by the chinese, the americans, the british, the malaysians, the australians, even the new zealanders. i don t think there s any failure of imagination. i think there are enough trained investigators who have real skills, who have done this sort of thing before that they re not going to go put on blinders at this stage. they are going to get to the bottom of this. it s going to take a long time, but they re going to get to the bottom of it. i hope so. david and peter, thank you for being with me. i freesappreciate it. still to come, the invest sgigs flight 370 and the investigation that hangs over the cockpit.
