recorder. is it at all premature to make these determinations that this is an intentional crash of a co-pilot? >> absolutely not. we didn't make it. the prosecutor did and the ceo did. let me remind you what the ceo said, i am speechless that this aircraft was deliberately crashed by the co-pilot. they don't make those sort of statements likely. we don't know why he did it, but he did it. >> and there is nothing that the data recorder can tell us different? >> not really. we're now going into the ifs and whys. it's going to show us the mechanisms. it will tell us was the cockpit door forcefully locked, in other words with the lock mechanism. it will tell us bits and bobs. but we know that he turned the altimeter from 38,000 to 100
