Wreckage when it is confirmed that it comes from flight 370, is going to give just two basic facts. one, the plane is in the water. two, we are looking in probably the right space. >> does this tell us down -- >> it's down off of perth. >> does this tell ug the plane crashed in the water while intact or there is a possibility this particular part dropped off ahead of the crash? >> well we don't know that yet. they're going to look at the fracture surfaces. and see under an electron microscope they'll be able to determine exactly how this plane -- this part of the plane separated from the wing....

It, the forces applied at the point of impact when this flaperon separated from the airplane. those fracture surfaces are going to not be optimum because it's been in the water for 17 months and has suffered corrosion. what the information they can extract we're not going to know until the metalurjigists have a chance a look at it. they will get as much information from it as they can. we're going to -- it's going to be a few days before we have an answer to that. >> captain, talk about the challenges we do face. as you talk about corrosion and different things being in the sea water for so lo...

They can then take that little piece they have, determine fracture surfaces, and maybe then put it on to the -- buildup of the plane and determine something that -- which part of the plane it cam from. of. without physical evidence you can speculate until -- >> which we tree to avoid -- we try to avoid. going on prior cases and what you find in the search is that there are reports of people, in the case of air france -- people who remember seeing a lights in the sky, a fire, flames. their recollection of points and places didn't jibe with what they ultimately found. but here, very little of th...

This piece will undergo extensive follow-on inspection at the ntsb's materials lab in washington, d.c. to facilitate that inspection in washington today, the structures group will begin laying out exactly where they want to cut this part out. we expect they will begin cutting it today. maybe even have it completed by today. to give you an idea what we're talking about, of course we said the fracture surfaces about five-by-one they'll go larger than that area. we anticipate the area to be cut out is eight or nine feet long by two feet wide. the way they will do that is they'll take a hand grind...
