Note, for those who prefer to obtain data through a more common channel, that the NTSB's involvement in this investigation appears in their list of
Foreign Investigations
The NTSB docket number appears on the draft transcript (linked at the top of the page) and appears to be DCA07RA059.
While I doubt the NTSB will release anything that the Brazilian authroities do not, they will of course release info in English, where the Brazilians would probably use Portuguese I guess.
