It is interesting (considering the source being the FBI, look at the URL!) but like many said, they just say what the investigator said. There is no citation of any audio record # from an interview or anything or any other proof. It is most likely something concocted for public display. Or the investigator went a little nuts after seeing those things crash and his imagination got the better of him.

I would like to see the documents concerning the actual analysis by scientists after they retrieved it!
