back to square one. >> if they get out there, they see the debris, they pick it up, they look at it, how do they make that link, that what is essential lly a blob on a satellite, how do they identify it as being from flight 370? >> they'll be hoping for some sort of markings, the livery itself will be critical. they'll be looking for any sort of debris which is specific to a boeing 777. that's the sort of things they'll be looking for. there may have been certain options or modifications or whatever done by malaysia which could help identify the plane. but a lot of it is going to be just looking at it and seeing that signature. maybe it's a livery. maybe it's a life jacket maybe with malaiysian airlines on it. it's that level -- they will get the radar pictures sure, but
